Greg,
I am not usually the one who defends PGmusic when discussion is about workflow, interface or "innovations", as you mentioned, long passed due.
I strongly support some of ideas you mentioned. Such as having musical segments that are specifically designed for intros, bridges, breaks and interesting endings, without jumping to other styles or some unusually "creative" methods, just to get there. Also some other points you made are very true such as the workflow.

However, I disagree on some things, such as 120GB of content is a lot.... These are live musicians playing! Not arranger midi styles (which I have nothing against too) By today's standards, 120gb is very affordable. You can get 256GB SSD drive for $40-$45 with a 5 year warranty.


I know that some people are not happy with recent 2019 version, but looking at the big picture, we are 64 bit now!!! I believe that is a very good start and a huge step to bring BIAB to place it deserves to be.
I hope that with future upgrades crew focuses more on interface, workflow, generation time improvement and bugs rather than new features.
