Just information on how we solved that problem in our own appliance / platforms. For FreeBSD it would need some tooling still to handle this style of updating, regardless of which pkg base is used. And for what it's worth, FreeBSD is all the poorer for not being able to bring modern language based tools into the base. Personally I'm hoping the shift to base-packages makes this a moot point since the idea of 'what is base' can be diluted to just a manifest of what gets installed out of box.

Additionally there is a runtime problem to solve. I.E. if you change flags mid-stream, and user updates, there was no clean way on pkg-side to remove those already installed granular packages.
