Did United quietly change the nonrev dress code? Leggings allowed now?

Checking in for a nonrev out of ORD tomorrow and noticed something interesting.

The old “no yoga pants” line in the dress code section seems to be gone. I swear it used to be listed pretty clearly.

Does that mean leggings are now fine? Or is this one of those “still expected, just not spelled out” things?

Curious if anyone else has noticed this change recently.
