I mean just to play the devils advocate. 

None of the NIPs are enforceable, so even if nip-09 exists, there's really NOTHING you can  do about a relay that doesn't honor it,  other than trying to make sure your note doesn't reach it, which is very hard since anyone of your followers can broadcast it to such a relay.  

Its really not much different than someone screenshot-ing your tweet. 

I like nostr:npub1wmr34t36fy03m8hvgl96zl3znndyzyaqhwmwdtshwmtkg03fetaqhjg240 's  take on being able to dissaciate from your note atleast as a signal.
