Tier 7 ratting anomalies

Hi.
Does anyone know why the tier 7 ratting anomalies, namely whatever pirate faction Ports, were removed from Nullsec with the Equinox update?
Were they just forgotten?

Equinox is CCP’s current attempt to make Null more ‘active’ by limiting the amount of farming that each system can support. They altered and removed a number of features in order to achieve that.

Ports were intentionally removed as part of their rebalancing of various spawns.

You can find multiple discussions of the effect of Equinox on Null. Here’s a fairly thorough one:
