There are several thousand people on the NANOG list, and public web archives.  I don't think this
is a useful question.

FWIW, I also don't think that repurposing 240/4 is a good idea.  To be useful it would require
that every host on the Internet update its network stack, which would take on the order of
a decade, to free up some space that would likely be depleted in a year or two.  It's basically
the same amount of work as getting everything to work on IPv6.
