Could I merge branch comment-cache into master, please?
I'm not John, but I wish we didn't hurry so much to merge experimental branches into master. The curly quotes feature comes to mind, and how it ended up very hard to back out of.
An alternative approach using the syntax-ppss cache has been discussed and tried. For reasons currently being discussed in bug #22983: (syntax-ppss returns wrong result) and the emacs-devel thread "Problems with syntax-ppss: Was [... Apply `comment-depth' text properties when calling `back_comment'.]", this approach cannot work.
This seems like a misrepresentation of the discussion in #22983. If anything, I'd expect the reverse conclusion: it's quite possible to make syntax-ppss stricter, and then base comments-cache on it.
