Summary

This pull request is proposing a new RFC.

To succeed, it will need to pass into the Exploring Stage), followed by the Accepted Stage.

A Proposed or Exploring RFC may also move to the Closed Stage if it is withdrawn by the author or if it is rejected by the Ember team. This requires an "FCP to Close" period.

An FCP is required before merging this PR to advance to Accepted.

Upon merging this PR, automation will open a draft PR for this RFC to move to the Ready for Released Stage.

Exploring Stage Description

This stage is entered when the Ember team believes the concept described in the RFC should be pursued, but the RFC may still need some more work, discussion, answers to open questions, and/or a champion before it can move to the next stage.

An RFC is moved into Exploring with consensus of the relevant teams. The relevant team expects to spend time helping to refine the proposal. The RFC remains a PR and will have an Exploring label applied.

An Exploring RFC that is successfully completed can move to Accepted with an FCP is required as in the existing process. It may also be moved to Closed with an FCP.

Accepted Stage Description

To move into the "accepted stage" the RFC must have complete prose and have successfully passed through an "FCP to Accept" period in which the community has weighed in and consensus has been achieved on the direction. The relevant teams believe that the proposal is well-specified and ready for implementation. The RFC has a champion within one of the relevant teams.

If there are unanswered questions, we have outlined them and expect that they will be answered before Ready for Release.

When the RFC is accepted, the PR will be merged, and automation will open a new PR to move the RFC to the Ready for Release stage. That PR should be used to track implementation progress and gain consensus to move to the next stage.

The Question:

• do we want to bring in the ember-cli-deprecation-workflow addon?
• or build the entire addon's functionality in to ember-source (behavior / usage would be unchanged)

It's possible we can do the first, and then the second, but the addon isn't very big (it's just one file, basically)

This is something I'm surprised has t happened sooner. From what I've seen, you kinda had to be 'in the know' to use deprecation-workflow, and it wasn't clear that it was the recommended upgrade approach, at least for those who weren't around during its early days.

+1 for baking it in. Or at least having an ember-cli command that installs it.

RFC Review (1) are in favour of this.

We discussed this today and people were in favor of swapping the design around to the "just use the existing addon in the default blueprint" because it would be a quick win. We can still do the alternative of building it into ember later.
