Whatever the IPv6 transition might require, it isn't comparable to the small effort needed to upgrade a few laggard OS's to support 240/4 and to do some de-bogonization in the global Internet, akin to what CloudFlare did for 1.1.1.1.
It may be a good idea to offer 127/8 for relocation. Even if
the range may be used internally by some devices (though, for
double NAT, rfc6598 shared address should be used), it is a
local problem for people using bogon addresses.
