There will be no future free-for-all that burns through 300 million IPv4 addresses in 4 months.
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.
