There is a lot of cross-library importing in the framework unit tests that I'd like to clean up, see the design doc for more: https://docs.google.com/document/d/1UHxALQqCbmgjnM1RNV9xE2pK3IGyx-UktGX1D7hYCjs/edit?tab=t.0 This PR cleans up a few obvious instances and adds TODOs for others. I created this while doing an investigation for the design doc linked above. I hope that we'll be able to follow up with fixes for all of the problematic tests (tracked in the issue below).
