Many recent PRs have required substantial revisions or been closed without merging and could be characterized as [extractive](https://llvm.org/docs/AIToolPolicy.html#extractive-contributions).

Thanks for the feedback. I understand.

I probably moved too quickly on some of the recent patches. I'll be more careful about what I open and make sure I've done enough validation before asking for review.

I'll also keep the weekly ping guideline in mind.

I'd still like to keep contributing to NVPTX, just with a bit more care going forward.
