You would need to validate all devices to support this 240/4 block that
most IP stacks today will not use.
I think starting down this road with the idea of making it like the 10/8
block would still be a win. I've seen enough companies running into grief
with allocation issues in the 10/8 block that the idea of having an
additional /4 block available, even if only Linux and routers supported it
would be very useful. (especially with container heavy environments)
As long as you validate everything that is being connected in there and it
never leaks outside (remember, that is hard, for example look at MS
leaking their internal IPs in email headers), you can do whatever you
want.
