Ah, okay. I was under the impression that the LMTX standalone
distribution carried a ton of TikZ patches and that ConTeXt patches
weren't really merged upstream, but it sounds like there are only a
couple small patches and upstream does merge ConTeXt patches. I'll
rebase my PR and check with upstream again. Thanks!

I've seen a few TikZ bugs/patches resolved on this list, and I know that
the LMTX standalone distribution carries patches for TikZ (although
fewer than I thought?), so this seemed like the right place to start.

I need to rebase my current PGF PR anyways, so I'll add this in with it.
