I am looking at this gitlab link, and they way it is implemented is
simply setting PROMPT in a way that adds these escape sequences to the
original PROMPT value.

In other words, it is a bit more advanced version of our approach with
setting prompt to a unique string - they surround the prompt with unique
chars instead.

In theory, we can do the same thing, adding some kind of invisible
unicode character around the prompt. We may even do it in the existing
prompts. Although one downside will be that the unicode character we add
may be carried along if the user copies the comint buffer contents.
