I can report that darcs (which makes heavy use of bytestring and even
includes a few optimizations based on an Internal module) works fine
with this version (test suite passes).

is quite amazing. I knew of allow-newer, but what is this "*:bytestring"
notation? Is that connected to the fact that cabal now unpacks
everything that depends on bytestring inside dist-newstyle/src? It
doesn't normally do that. That was quite helpful because it meant I
could easily fix the (only) error by locally by changing the import of
ByteString.Builder in
dist-newstyle/src/Cabal-3.2.0.0/Distribution/Utils/Structured.hs and
then running cabal build again.
