It would be a subtle unexpected semantic change, that we would need
to copy linux-abi and document etc.  I'm not convinced it is that
useful.

I'm inclined to keep the semantics pure until there is some real
experience from the field on issues like this.

Sounds good.  Mentioning the user namespace was just to make it clear
where it should be fixed.
