Understood that these would be duplicates, and I certainly don't want to put more pressure on you, but I think there would still be value in having a known reporting channel for people to say "I am also affected by this":

* MS Developers get a more objective feel for the scale of the issue.
* Users who report the issue can track progress (they will presumably get told *what* their report is a duplicate of, and can follow the underlying issue).
* Python package developers have something definite that they can offer to users.

My suspicion here is that MS simply doesn't have a user-visible support channel for the Store Python stubs, which is why we've ended up discussing this here.
