It doesn't really matter...  ALL of these software kernels receive
updates frequently;
mobile and desktop OSes in particular have numerous updates per month, and
even BSD, Cisco, Juniper, Arista  OSes  have frequent updates being made.

Adjusting the disposition of 240/4   in the kernel is a minor change.
Likely  less than  1% of the change volume  these systems' codebases
receive during the average month.

1 or 2 lines of code for vendors to adjust --- not a huge deal
(so long as it is software and not hardware/ASIC logic that needs to change).

That is likely less than the amount of text that needs to be altered in the
RFCs to state that  240/4  be reclassed as  global Unicast.

Certainly not at a comparable level of complexity as implementing V6.
