I agree also that some “Parachain Technical Fellowship” would be good for this role (as well as others).
Parachains would probably want their local governance track that would lock their parachain to be shorter than the collective’s track to re-set code/head data, since the same power that can unbrick a parachain can also brick one. Then, if the para is “alive” and sees a referendum come up regarding itself, it can lock itself to prevent the substitution.
