Of course they are moving forwards - the comment period is for constructive comments on the method - not pointless requests not to implement anything at all, which seemed to comprise the bulk of the responses. The next phase is to finalize the requirements and mechanisms.
I have always thought that the NPRM was just a pointless federal agency requirement/procedure to implement Remote ID. Smoke & mirrors. Is the concept needed, yes, was the affected public really considered/invited, no. The list of providers pretty much speaks volumes. This was decided some time ago.
As stated, finalization is all remains.
