> very off putting and unconstructive

One of those is irrelevant and the other one is false.

There's a lengthy, clear description of a problem, with a use case, leading up to a feature request...how is all of that "unconstructive"?

In fact, what's definitively unconstructive is the way the feature request is closed: dismissing the use case as invalid, despite the fact there's a description of the rationale behind it in the comments.
