When using on GHC, 15 boot modules are always recompiled on startup.

I think we are not setting the HscEnv properly via ghc session deps.

The recompilation reason is reported as "missing old home dependency" which stems from here: https://hackage.haskell.org/package/ghc-8.10.2/docs/src/MkIface.html#local-6989586621680922934
