[process] Users unable to follow breaking change process

[itsjustkevin]

Problem statement

Users are not able to follow the breaking change process.

Step one of the breaking change process is the announcement. In the current state, users are not able to notify other users that a breaking change is incoming at the email provided (Dart Announce).

Example

Example case: https://github.com/dart-lang/sdk/issues/50710#issuecomment-1477075408.

Recommendations

• [x] Set the email group preferences to work through approval.
• [x] Create breaking change request issue template (https://dart-review.googlesource.com/c/sdk/+/290605)
• [ ] Update breaking change documentation

Changing the group setting sgtm, but we should probably expect to need fair bit of moderation/spam. wdyt @athomas ?

I've updated the group. The spam filters are pretty good and with the volume on dart-misc being low I hope this won't be any higher.

@mit-mit do you know if we have a process for feature requests already?

[mit-mit]

Not a formally written down process, but it's basically just "write up a new issue explaining and motivating the use case".

Thanks, I would like to get this recorded in documentation, I will open a separate issue to track.
