I don't have an opinion on whether the overall feature design
is well-chosen. But the mere fact that Unicode updates will
from time to time change the behavior (presumably only in edge
cases or for previously-unassigned code points) doesn't strike
me as a big enough problem to justify saying these functions
can't be marked immutable anymore. Especially since we have been
faced with that problem all along anyway; we just didn't have a way
to track or quantify it before, because locale changes happened
outside code we control.
