Well, Q6 proves my point.
There's nothing better than BIAB for traditional electric / acoustic genres for the Q5 item.

"how many people out there making music in a DAW even know about Biab and the BBPlugin"

Fewer than it deserves for sure. From Bass Thumpers post #808674 AI gave pretty reasonable explanation in Q3 answers 1, 2, 3. Especially 2+3 which can easily be viewed as one item. Smooth (bugless) workflow is everything.

Marketing has to do a bit with it too. No demo, not on popular sites like Pluginboutique, BigFish, etc.

If one yearly release would focus on just fixing bugs, improving workflow / limitation and bye bye to redundant menus and features that would go a very long way.
