AS is being worked on. Patch notes show fixes. test server threads talk about problems. 10 days ago filaments were removed from test server markets. 2 days ago the filaments you can find in data sites (on the test server) stopped working, and this was reported to be fixed. I think these problems are signs the developer is experimenting with some changes. It’s anyone’s guess if future changes make anyone happy. But these observations say the feature is not abandoned.
