KAPT being replaced with KSP (which breaks a whole bunch of stacks)

We get emails saying hey, you gotta make this change in a few months or we'll be delisting you.

Most of the popular libraries end up being replaced with bits and pieces of Google Jetpack. This is a lot softer, but we've spent weeks just updating dependencies because it breaks things in chains. We've had hours long pair programming sessions trying to debug some abstract error message. You can't replace a small piece, taking one out makes it collapse in strange ways.

The moral is don't expect Google to keep anything consistent (except Gmail I guess). But it also makes for decent job security.
