Yeah, that's all fair. Admittedly, I never use history expansion, so I'm
not thinking about how it could be useful in a given context. May as well
put 'set +o histexpand' in my .bashrc and call it a day.

When messing around in interactive mode to test things I may want to do in
a script, it's nice if it actually behaves the same. There are probably
some other set and possibly shopt things I should have somewhere if that's
what I want.
