Approving with a caveat that Don's suggestion will be taken.

On second thought this is best refactored as a separate message (diagnostic message) such as in https://github.com/microsoft/vscode-python/blob/77e9e63486b668c673def9e0b1f98fec9bac2868/src/client/application/diagnostics/checks/powerShellActivation.ts

I know its too late, but the diagnostics messages was the preferred approach, and we seem to be deviating from that.

See other diagnostics in src/client/application/diagnostics/checks

I believe we can still do this & is best done now, for consistency.

Sorry about that, but as all the work has been done and as we've to merge this before next release, I don't think re-writing most of the stuff in the name of consistency makes much sense at this point. (also I will be OOF starting tomorrow)

However this is definitely something to keep in mind from next time onwards.
Files virtualEnvPrompt.ts, condaInheritEnvPrompt.ts, extensionSurvey.ts and more deviated from the diagnostic approach.
