Hmm. I use arm64 macports instead of homebrew, and as far as I know, I download prebuilt binaries from macports without issue even on Tahoe -- are they signing them with an approved account? Or did they force me to build everything from scratch, like the old days, and I haven't noticed?

This doesn't affect most prebuilt binaries. It specifically affects what Homebrew calls "casks," which are redistributions of .app bundles (which come with additional restrictions via Gatekeeper, unlike a "simple" binary).
