If an SPF-type lookup succeeds, clearly the domain does exist. This

But the TXT-type lookup could accidentally fail due to resource
constraints on the authoritative name server or on the resolver.
Or TXT requires TCP while SPF works with UDP.
If the TXT-type lookup fails, shouldn't a PermError or TempError be
returned?
Exactly my thought.
I don't see any PermError. A TempError would be a TXT timeout before
the "good" SPF reply without v=spf1, that can't happen, or can it ?
