We generally only worry about known users (such as upstream itself). If someone has a use for a deprecated extension, they can comment on PR that removes support and propose an alternative: either plain revert or something else, depending on the level of maintenance necessary.

So in short, I'd prefer to first land this as-is (with the two extensions coexisting for a very brief period of time), and then follow up with a PR that drops the vendor variant. Could you prepare a PR that drops the NV version?
