"Perhaps now the winds are changing"

I think that's because we got most of the big items, such as:
More tracks, Partial (near instant) regenerations, MTP Library, Track view and whole bunch of others.
Now, time is ripe to refine & consolidate those features, focusing on eliminating bugs, redundancy and tuning things for optimal standardized workflow.

P.S. I don't care what language BIAB is written in and dirt cheap storage makes footprint (size) also irrelevant. Main thing now is user experience. A bug (+workaround) free & intuitive workflow.
