Why is it problematic? Its described here:

It’s pretty dumb that you need to spam your timeline with two events: highlight + quote repost just to do a quoted highlight. The nips repo is just opinions from random devs that have zero interest in the needs of your users.
just because a nip isn’t accepted over there doesn’t mean you’re not allowed to implement it 😕
If its a good idea then it will naturally be implemented, regardless of if some centralized repo approves it by fiat
