    Yes, but the name "compilation-minor-mode" hardly addresses the DWIM
    nature of next-error as it stands now, and the compilation-minor-mode
    has other side effects (fontification, for instance).

Those go together because they are used together.

Introducing unnecessary levels of abstraction for small things
creates clutter.  We do not want a separate mode for next-error
parsing alone, distinct from the rest of error handling.
