We could. Honestly, the underlying reason we don't is at least in part
that that makes the behavior differ more from the behavior of "sudo";
with sudo, you see actual ownerships. But that's less applicable here.

I would be more inclined to report a Definitely Absolutely Not Okay
user ID, like 65533. (65534 and 65535 have both been used as Magic
Cookies in the past, I think.)
