what CI cycle would that avoid

For me at least I wouldn't expect to re-run tests locally after bumping Unicode or similar, while I probably would "happen to" re-compile with something like x.py check, which a static assert should catch and tell me to update this, vs. here where I need to push a PR and wait for the CI to fail and then push a trivial update.

But not a big deal anyway.
