Packagers are already doing things this way, the packaging guidelines
mandate this subpackaging approach if one wants to continue shipping the
sysv scripts, and "yum install pkg pkg-sysv" will result in this
scenario taking place on upgrade.  So in my opinion either this scenario
must be supported, or the sysv subpackage approach banned.

I dislike it as well, but on the other hand I believe my proposed
scripts will work just fine in this scenario too - I'm basically just
trying to come up with cases where sysv scripts might be around and
cause problems.  Why I'm doing that is a result from Toshio's earlier
post in this thread in which he said "we don't prevent people from
packaging systemVinit scripts ...".  I have no problem dropping this
test case though.

Right, I listed it just for completeness (so that
pkg(systemd)->pkg(systemd) upgrades don't touch possibly existing sysv
stuff).  No problem for me dropping this test case either.

Yep, same thing as for the #5 vs #2 thing above.
