Yes, Definitely

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
issued,
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.
