Thank you :) It's been an honor to help out with such a useful project.

I think this would work out really well... Migrating library functions
together would help ease the transition over to the new code, which could
be done in gradually and in parallel. With core support, the various
worker modules and daemons could be brought to parity as testing permits.

Having a good version-specific baseline to compare the trunk to really
helps, too. It'll make the commit-analyzing and diff-wrangling a lot

The more I think about it, the more I also like Adam's idea of assigning
point release versions to various functional milestones. We can focus on
the core compatibility and flesh out the component support one block at a
