Is this considered a breaking change? Also could we incorporate this language in the release note?

With this change we will only accept lowercase alphanumeric characters and - , and names that start and end with an alphanumeric character. All other characters will be considered incompatible.

This isn't considered breaking since there is nothing existing at a GA level to break (v2 resources are in beta and v1 resources are not affected). Since this is only on the main branch and not tagged to be back ported to 1.17, it should go out in the 1.18 time frame.
