Agreed, so the change would look like this, right?

@Maintainers: How do you want to proceed with this proposal?  Do you
like to ask John W., or should I prepare a patch and send/install it, or
anything else?

For bonus points, I offer to delete the unnecessary ":group 'align" in
the defcustom's in align.el.

Please advise.  Thanks.

Best, Arash
