One of the main reasons why I'd been hesitant historically to do this is
that I was worried about encouraging library maintainers to do complex
transitions for existing shared library packages that don't follow this
rule. Converting from multiple shared libraries in one package to
multiple packages, one per shared library, when there hasn't been an
SONAME change was surprisingly difficult to get right.
But maybe we can handle that by just adding a long explanation to the tag
description.
