Some widespread IPv4 stacks refuse to handle these addresses, so
nobody would ever want to use them on the public IPv4 Internet.
That will be a bit of a challenge in private networks too :-)
Much smaller. If example.com wants to use them, example.com will have to
upgrade its own computers and routers to a version which supports this
new class E. Nontrivial, rather expensive, but doable.
If you were to get 240.24.42/24 from your RIR, most/all of the public
internet would have to upgrade before you could use the addresses.
(Kind of like IPv6 but with a piddly little address space.)
