This makes sense, whether or not the particular registrant is named.

Presumably the registrant would be given some sort of non-repudiable proof
of their registration which could be shown to a third party, but the draft
doesn't require this nor does it cover the case where such proof is lost.

Given that the target market for local addresses are typically those who
would normally not be RIR members, it seems illogical to let the RIRs set
policy over consumers who have little or no representation. For lack of a
better body, the IETF should retain control.

A return could be effected because the registrar necessarily knows who it
assigned each prefix to, even if that information is not published. I don't
see how it would be possible for a registrar to discard this information,
since the registrant may want to make changes (eg. DNS, WHOIS) after the
initial assignment, or transfer it to a third party.

Section 7.0 of the first draft seems to cover this adequately.

The presence of WHOIS entries should follow the same policy as DNS entries.
WHOIS has an interesting corner case, as the registrar may wish to indicate
a prefix is assigned but not to whom (see first question).

I thought the difference was implicit in Section 4.0 of the first draft with
the general ban on inter-domain routing absent specific exceptions; this is
signiticantly different than merely not guaranteeing routability of normal
unicast prefixes (which is a case of the RIRs covering their asses since
they have no control over ISPs).
Is there a stronger wording that makes this difference more explicit?
