Ultimately the goal should be making the "traditional" scriptlets
extinct to the point that using them requires an exception.
I've no illusions here, it's going to be a long long road and require
further enhancements to rpm (for example dealing with users and groups)
but that's what the long-term overall goal should be.
I was wondering about the case of users and groups in scriptlets.
Something I would like to investigate next time I dedicate free time to
Fedora is conditional and one-shot services with systemd.
Maybe some of that complexity could move from the package manager to the
service manager. For the use case I have in mind it's definitely the
service that wants the user and group, because none of the installed
files need them. It's only a runtime requirement for the service.
For the case where the packaged files don't need custom user/groups, you
can (and probably should) use systemd facilities already: see sysusers.d(5)
That doesn't help with packaged files though, unless split into a
separate pre-requisite package which is a bit heavy solution for that.
