Will niyamawali clarify what kind of rights this new NRN nagarikta holder will have? I was under impression niyamawali is only a guideline on how to issue these to NRN applicants.

Exact rights of new NRN nagarikta holder will still be gray area for sometime unless some lawsuits start popping up, and court starts clarifying those or house passes law to clearing further. But regardless they can’t be involved in political process and be govt employee. Everything else seems to be in table.
