I think it has been discussed at various levels, but would likely have 
been dismissed for one or more of the following reasons:
1. A lot of people filter packets and/or prefixes 224/3 or 240/4 out of 
habit, right, wrong, or otherwise, so space from 240/4 is likely to have 
lots of reachability problems.

2. The effort expended by people to solve reachability problems from space 
they'd get out of 240/4 would be better put toward moving to v6.

3. Busting out 16 more /8s only delays the IPv4 endgame by about a year.
