And they recently released the Safari MCP in STP as well.

Looks like the Safari MCP is also now available in the most recent Golden Gate beta part of system Safari:

The team has been on a roll lately with massive fixes & improvements.

Like last months announcement of over 500 fixes.

Does this help stable Safari in any way? I have a WebKit bug I’m tracking that’s fixed in STP but not in stable and it seems like there’s no telling whether it’ll ever land.

This update fixed some web inspector bugs that I reported, but I can't use it because Safari Technology Preview inexplicably supports fewer macOS versions than Safari itself, i.e., no longer Sequoia.
