Don’t worry, that response wasn’t directed at you, just at continuing the discussion in general
They were able to do this because it did not alter invariants (such as EVE Gate being closed) or impose retcons or introduce inconsistencies. Actually, it was fully compatible with the pre-existence of precursor races (at least one known for each of the five major races in existence, Drifters in fact being a precursor race) and the evolution of technology in general, as well as the rediscovery of ancient technology which is far more advanced to the current technology for reasons clearly established in lore.
Your specific line of thinking has some merit that I am amenable to.
In my most humblest of opinions *brushes shoulders off*, this would be acceptable only if a novel was written in which it was briefly opened and closed and the novel discussed circumstances around that (esp. empire politics in which they all rush toward it and basically battle over it politically and/or militarily similar to how Empyrean Age spanned for four empires, CONCORD, SOE, and Jove), and that no meaningful data emerges from the gate because access is one way only (not even telemetry or communications comes out) AND/OR whatever comes back is ambiguous, corrupted, mentally deranged, incoherent, etc. Also, the novel should neither confirm nor deny the state or even existence of Earth and the universe on the other side if anything or anyone comes back out of the EVE Gate. The one-way travel and lack of telemetry/communications would make sense given that no cataclysm is taking place (a second time), but intrigue and mystery could be further added to the EVE Gate if, for example, an artifact (and maybe some incoherent logs) were to emerge from the gate upon closing as the sole exception to the one-way-travel experience since we we won’t know what the artifact is is or how to interpret it (or the incoherent logs).
In other words, this novel would open-and-close this lore ‘violation’ for a brief instance and then things would return to the status quo. This I would actually be okay with and would probably enjoy reading the novel, though I could just as easily live without this invariant ever changing. As a matter of principle I’d rather not alter this core invariant, but were it to be altered, I think this specific approach would be sensible.
With Jove we have the exact same problem as the EVE Gate, except possibly to a greater extent. The only thing more mysterious and intriguing than a complete absence of information is tantalizing tidbits of information knowing that you will never get more than the paltry sum you already have. PLAYERS getting more exposure to Jove via access to their space (whether it’s incremental, via temporary event, or even in isolated instances like abyssal space) severely erodes the mystery and intrigue… Interacting with Jove should not become a normalized aspect of EVE as you could hop into any other wormhole or join an Incursion fleet or enter Abyssal or hit up mission agents.
I want to emphasis the keyword “players” a second time because this would not be a problem if Jove were to continue to be expanded upon directly via canon lore such as novels. There is a huge difference between expanding Jove lore via stuff like novels and via direct player interaction exposure. Expanding the lore makes the steak that much juicier but continues to keep it out of our reach, so we keep on salivating - which is a good thing… but once we get our steak and consume it and there’s nothing left, then it becomes “meh”, been there done that, Jove isn’t fascinating anymore.
Basically, I think it’s fine if Jove is expanded via lore but not player interaction (save for SoCT ships). As for the EVE gate… I think you’ve identified a narrow exception for which maybe a novel could briefly open and close the gate. I just don’t want there to be a permanent situation like when they killed Empress Sarum via live event… that pissed me offfffffff.
