Because that might take years to happen, or the packager might never
do it at all on the theory that what is good for customers in general
is different than what's good for one particular customer, or on the
theory that it's just not a high enough priority for that packager.

Are you seriously saying that you've never needed to customize a
startup script on a RHEL box somewhere?
