Pardon me, but when I see something like this, I investigate. The attribute-policy.xml wasn't working as expected.
I understand the scopes I might get. The only valid ones match the more restrictive pattern.
You're welcome to join a Zoom meeting with me to go over it. Or I can send you my complete configuration.
It's pretty vanilla. It's up to you--if it were me, I would at least verify the behavior and document it.
Or remove regular expressions--standard and well-understood in computer science--if you feel that way about them
Anyway if you have time, I'm willing to go over this.

To restate something said in a side discussion:  If you can you'd be very well off just using straight string comparison here - I assume you understand all the scopes you might get.

You obviously speak regexp better than I, but I maintain that regexps are usually a gun&bullet in search of a foot to shoot.
