I wonder whether it would be possible to add a simple catch-all command that would encompass a set of options that can't be defaults but that make writing shell scripts easier, e.g. set -euo pipefail, nullglob, inherit_errexit, extglob, assoc_expand_once, and various other settings.
It's annoying to enable all these settings individually, but enabling them by default would break existing scripts. How about something like "shopt -s bash2025" that would succinctly set these options all at once so that script writers can more easily opt into modern behavior?
