To me this doesn't look like a new feature, so I don't see the feature freeze
blocking this formally.

But there is also no rule that everything that is formally permitted /has/ to
be done. The time after the feature freeze is also useful to get some field
testing by the few early adopters, and providing an effectly moving target
there does not really help the cause.

Recently there were two serious regression on the Qt side due to "just using
string views" (which would also be formally permitted), and I've seen now a
patch that changes a map to a hash to avoid part of the porting "work" to the
new comparison scheme that makes that change not quite "mechanical".

So, sure, in a perfect world, this kind of activity would be neutral,
but apparently it is possible to fumble.

Maybe I am just generally lacking a certain sense of urgency here to have
this kind of changes, but I think it would be better to avoid the risk by
simply not doing it.
