Surely this is a sign that this is a worse solution? The header isn’t a
part of distextract any more than partedit, so this is entirely
arbitrary. It also blocks the ability to do the subdirectories in
parallel with each other.

I would much rather this reverted; this feels like a regression to me,
with the only justification being that it “is bad”, according to your
commit message, but so is this, and I would argue it’s worse.

Or go put it in its own common directory.
