I believe the intent there, instead, is to encourage RIRs to hand out
large enough blocks or do sparse enough allocations that a non-contiguous
block is not necessary.

Yes, but, it should, where possible, attempt to do so without requiring
sites to renumber.

Another key provision of this draft which I think is somewhat important
(albeit unlikely to have much real world effect) is that it provides formal
recognition that address assignment policy is an RIR public policy issue
and not an IETF design or IAB architecture issue.  The RIRs will make
address allocation policy, and, if necessary will ignore IETF overreaching
in this area.  I think it is better if the RFCs provide recognition of
this reality and do not overreach.
