Going to take awhile before this happens. This is a draft NPRM. They'll have to finalize it, issue that actual NPRM, have the comment period, address the comments and then issue a final rule. Then we'll have to wait for manufacturers to develop and certify compliant aircraft (for flights over people). Lastly all of this is contingent upon implementation of remote ID, which we have not even seen a draft NPRM for yet.
And so there is no confusion this applies to Part 107 pilots/operation only. It does not apply to Recreational sUAS operations.
My best guess is this is 12 to 18 months out from full implementation. But it is a nice step in the right direction.
