A couple of months ago my then employer went to arin to get a direct v6
assignmentment. on the basis of the number of pops the resulting
assignment was a /43. It'll be a while I imagine before another prefix
is required.

Ah, I follow your reasoning. I'll be interested to learn whether the
numbers agree. ARIN staff has reported before that the vast majority
of IPv4 end user assignments go to organizations which do not
subsequently return for additional assignments. In general it's the
ISPs who come back for more allocations... I wonder if the minority of
end-user orgs who do request additional space request enough
additional blocks to make a difference in the routing tables.

Well, between that, and, the fact that ISPs should be asking for additional
space a _LOT_ less frequently and all cases should be more likely to
get an aggregable expansion of their allocation/assignment now that
we are delegating by bisection, I think both of those things will reduce
the rate at which growth within organizations increases the routing
table by quite a bit.
