I think so -- it' unlikely the value will get accidetnally changed, but
if it does it's only going to get caught if you enforce the value.

And really, what's the point of updating the annotations in a stable
release if you don't enforce the value? Annotations are only really used
for config review and enforcing config values, and we don't do config
reviews for stable releases.
