Yes, but isn't --finish supposed to be run only once these files are not
within a sysroot any more?

Exactly.  For some use cases it is "normal" to have this native
development later.  (Example: most distribution packagers.)

That's exactly what I'm trying to find out.  If it's a packager task, it
needs to be documented as such, and if --finish is not the right place
to do it, then we should invent another tool to easily to it, because we
can't expect people to get those sed scripts right themselves.

Good point, yes.
