% The RIR policy is to reserve the whole /29 for expansion of the /35.
% They promised never to allocate parts of the same /29 to more than
% one user.
%
% Therefore, the /35 can be announced simply by announcing the whole /29
% that contains it. There will never be anyone else in that /29, so there
% is no need to announce the longer prefix.
%
% We must establish this principle solidly now, so that we **never** see
% holes punched in /29s.

This has its own set of problems. See the current discussion
on micro-allocations inside ARIN. In IPv4 parlence, it seems
a tremendous waste of space to delegate a /19 for a site that
will never have more than a few hosts yet will be multiply
homed. What I see here is the same argument, a /29 for a small
set of nodes that will -never- meet the growth prospects for
numbers of end-nodes. Historically this was also the case for
IPv4 and its design, pre-subnetting. It became clear that
there would not be a small number of networks with millions of
nodes. Hence the initial subnettting model (class A/B/C) and
the CIDR refinements.
Is it just me or are we failing to learn from history here?
This looks like a small number of networks with order(n) number
of end-systems... all over again.
