Well, to turn this around: what benefit does the systemd-sysv-convert
tool bring regarding the migration path? I don't see any. (note that
this tool is -- despite its name -- not a tool that wil convert sysv
scripts to systemd units. Not at all. It's supposed to record in which
runlevels a service was enabled before the migration for reference by
the admin later on (this is stored in the file
/var/lib/systemd/sysv-convert/database).

If we drop this now then the migration certainly becomes a bit easier,
since the scriptlets become much shorter, and easier for people to
understand -- and who likes rpm triggers anyway?

Note that systemd-sysv-convert is a tool that is supposed to be useful
for admins, not for packagers or developers. And I simply don't see that
admins accepted that tool and ever made use of it.
