I'd like to follow this with a more precise proposal. Namely, redefine
the current profile statuses to apply the following:

a. stable -> fully tested, all depgraph breakages are errors,

b. exp -> fully tested, all depgraph breakages are warnings,

c. dev -> developer's playground, not tested.


This would specifically mean that:

1. Any 'exp' profiles with serious breakage will temporarily be
downgraded to 'dev'.

2. A 'dev' profile can be upgraded to 'exp' if its scale of depgraph
breakage is reasonable (i.e. doesn't clutter the QA report with too many
warnings).

3. A 'exp' profile can be upgraded to 'stable' only if it has no
depgraph breakages.

I don't have a strong opinion on whether we should pursue marking all
profiles 'stable', or if we support keeping 'exp' indefinitely.


The CI would be updated to test 'exp' profiles and report staging
warnings appropriately. Repoman would be updated to have warning-class
dependency.badinexp (like it has for .badindev right now) and to check
exp profiles by default.

Your thoughts?
