Yes.  An unversioned conflict would make the whole cross stuff
effectively uninstallable.

This is what I implemented as well, a symlink farm.  But those symlinks
needs to be belong to the same source package, as the set of required
symlinks change over time.  Or we are back at: requires conflicts.

I only consider symlinks to files acceptable.  With symlinks to
directories we are back in aliased directories land, with all the same
problems as merged-/usr.

Only if the *-cross maintainer is fine with updating it within a day,
every week or so for unstable, but even for stable or security.  So, not
possible, given that the existing conflict for the same reason against
glibc was only solved by NMU after a week or so.
