this is correct not necessarily because of the reasons you state, but
because all the RIRs have changed their ipv4 allocation policies to
policies which assume complete or near-complete depletion of the
available pools, rather than policies which allocate / assign on the
basis of stated requirement. For sure, organisations were previously
requesting more than they needed, but if stated-requirement were
reinstituted as a policy basis, the address space would disappear in a
flash.
The point remains that 127/8, 0/8, 240/4 are problematic to debogonise,
and are not going to make a dramatic impact to the availability of ipv4
addresses in the longer term. Same with using the lowest ip address in
a network block. Nice idea, but 30 years late.
There's no problem implementing these ideas in code and quietly using
the address space in private contexts.
