My other thoughts, I should add:

*   We could also just tighten the rules for link ref IDs all the
    way, and outright ban literal `[` and `]` chars in the IDs.

*   Even if we allow them, it might be easier, both in terms of
    code and documentation, to simply state that they must be
    backslash-escaped.

After a few more minutes of thought, I'm having a hard time coming
up with a good reason why `[` and `]` shouldn't just be banned
characters for link ref IDs.
