No  (well,  only to a limited extent)

Yes, Definitely.

In the case of IPv6;   slightly too small of an allocation can do much
more damage than slightly too large of one.

In other words:  the logic is almost the opposite of what IPv6 was.
A prefix longer than say a  /32;   should    not be allowed to be

without evidence of  "Justified non-need"  [  because it is at too
great a risk,  that the applicant might some day need more addresses
-- resulting in the use of an additional routing slot.]

"Justified non-need" --
In essence,  a guarantee  signed in blood that no more space will ever needed,
even in the event of a network redesign,  acquisition, etc.

Longer  prefixes should require  more justification that no more
addresses will be needed, than shorter ones.
