TBH, it seems to me reasonable that we just do this.
If our position is that we actually expect Fedora package scriptlets to
be executed by bash and don't think it's a problem if they don't work
when executed by some other shell, why not this make this clear and
explicit in this way instead of having the default be sh, but then tell
people sh must be bash?
One caveat: I'm not sure current RPM allows this to be configured
separately for builds versus installs.
There's a %_buildshell macro as of 2.4.101, but this only references
%prep/%build/%install/%check/etc...

...seems like the default for unspecified %pre/%post/etc scriptlets
might fall to the compiled-in /bin/sh. And the configuration of *that*
might be the rejected proposal at
