While we try to protect rpm from these footguns (in the context of rpm), it'd be better to not have them at all.

rpm.execute() which we have for five years now is a far saner and safer interface for executing helpers, both to the user and rpm itself.

We should add deprecation warnings in 4.20.
Actually removing these belongs to v6.

Document fork, exec, wait and redirect2null Lua functions as deprecated
85b5ea6 
Rpm scriptlets should have no business dealing with this level of
detail in process control, rpm.execut() is much saner and safer
for scriptlet needs. We can't just remove because this is a public
API with known users (eg glibc in Fedora), but we can at least document
these as deprecated.

fork() and exec() are the main "problems" here, but wait() and
redirect2null() become meaningless once you take the first two away.
