Is this a request to publish package:analyzer with SDK constraints like this?

environment:
  sdk: '>=2.17.0 <4.0.0'

Or just publishing the current state as is, with

environment:
  sdk: '>=2.17.0 <3.0.0'

...because the only thing that we need is the updated ExperimentStatus.currentVersion to be 3.0.0?

It seems that using 4.0.0 might be too soon, because I don't see any other packages, including analyzer dependencies to be published with new SDK constraints.

I think this is a request to publish a version of analyzer which understands that the "current language version" is 3.0.0

Yes, the current language version is now 3.0.0.

Yes, I guess we can update the version constraints later.

[scheglov]

Done.
