If all it meant was that currently cached content would effectively be
expired, I wouldn't see this as being anything more than an strong note.
But as I'm sure people have created their own tools for building the page
cache keys to forcibly expire them [and not yet taken advantage of that
function being separated to a util module] I'm guessing it'd warrant a
warning to catch up.
Just my 2c.
