I don't recall any significant discussion of this on tech-pkg.

I don't think you've thought this out very well. What happens
when you upgrade a package containing shared libraries? It looks
like the old shared library will end up not being registered to
any package, and therefore, in the case of a soname change, the
preserved +REQUIRED_BY will be a complete lie (not that the 
present "pkg_delete -u" does any better).

I've proposed a trick, where the delta files gets registered to
a package with a transformed name and the dependencies get shifted 
to that package, and implemented it as a wrapper around the package
tools. Please see PR pkg/10835, and follow the references therein.
