Yes, $? is not needed.

exit or return is equivalent in this case though because of set -e.

I consider all commands critical, and if one is allowed to return
unsuccessful, I'd rather explicitly allow it with something like:

can_fail || :

I'm still curious as to why set -e is stripped in the first place?
