I'd be inclined to agree (or at least voice the same concern) as Renato
here - as a project we don't really have very good bug hygiene, so adding
more bug filing doesn't seem to me like it'd give us much value.

Auditing existing XFAILs can be done today without filing bugs for them.

And we still always have the option to (& in many cases do) file bugs for
XFAILs to discuss them, etc.

But I don't feel strongly about it either way, so happy to leave the folks
who do to make the call/do the work.
