SPF doesn't have sub-domain level protection like DMARC does, would it be useful to look at adding it?
I doubt it. SPF was written and implemented a decade ago and it's unlikely anything new would be widely deployed.
DMARC sub-domain level protection assumes that the owner domain isn't a TLD. Can we change that to add a lookup on the TLD?
Depends on what's in the PSL for the domain. It seems to me that if the owner domain is the TLD, that tells us it's a single-user vanity domain, so you can make your DNS do whatever you want.
