If you read that part II, it only activates the lifetime background check and the automatic ATT changes.
Nowhere in Part II has the proposed NR transfer regulations been activated, which was OP's question.
July 7th is when certain provisions (but not the NR transfer regulations) were activated.
No, there are no legal grounds for the CFP to refuse your request for license verification or impose the requirement that you inform them what you are transferring to them.
That said they can still take you for a ride if you make a complaint that slowly winds its way up the chain. Instead of having an ombudsman to make a complaint to.
