Indeed that is exactly what has been happening since the initial
proposals regarding 240/4. To the extent that it is now largely
supported or available across a wide variety of gear, much of it not
even modern in any way.
As someone who has been involved in the deployment of network gear
into class E space (extensively, for our own internal reasons, which
doesn't preclude public use of class E), "largely supported" !=
"universally supported".
There remains hardware devices that blackhole class E traffic, for
which there is no fix. https://seclists.org/nanog/2021/Nov/272 is
where I list one of them. There are many, many other devices where we
have seen interesting behavior, some of which has been fixed, some of
which has not.
cheers,

And I am sure you would agree that un-reserving a decade ago would have
more than likely resulted in a greatly improved situation now. Along the
lines that doing so now could still result in a greatly improved
situation a decade hence. Should we still need it.
