clang.debian.net lists 39 instances of these, though I think the buildd
is a bit behind so there are probably a few more. I think it's still
worth reporting.
The case I'm personally aware of whose upstream maintainers were
historically most attached to its uses of nested functions and where the
changes to avoid them were most complicated was GRUB. In that case,
Vladimir and I recently removed all the uses of nested functions
upstream, and the 2.01 release will not use them. If it helps you to
make arguments to other upstream maintainers, here's the rationale I
posted for pushing this work:
