I guess I'd vote to either say they MAY or just note that it occurs in practice.

Exactly.  The origin server doesn't notice because nothing changes.

Right.

URIs definitely can become too long (phones are more limited than
desktop browsers, as are the gateways in between sometimes).  It's
also to prevent casual snooping, and finally, we use our own URL
parameters, so we'd have to ensure the user submitted form values
didn't collide with ours.
