Oh, good point, I'd forgotten that for multiarch the symlink is
architecture-dependent. So yes, the -dev package is inherently
architecture-dependent.
We can't move the symlink to the shared library package because then the
shared library packages aren't co-installable.

Correct. Anyone converting a library to multiarch should already be
moving them, IMO. I have with all of mine.

You're right. -dev packages are going to have to be multi-arch: same.
I think the hardest problem is then going to be the documentation
(including man pages) that are normally now in the -dev package, and any
-config scripts or the like. We already have multiarch path solutions for
header files and for the symlinks, although it requires duplicating the
header files for each architecture.
