I was asking if the category should be more coarse than this. But if you 
think this one's okay, great!

Yes, shouldn't be hard.

Oh, that's a bit surprising: going by the docstrings (the 
`completion-styles' docstring, at least), the values in 
completion-category-defaults are supposed to "override" 
completion-styles (which I take to mean "replace"), not just get prepended.

In this case, either way's fine, but there's a discrepancy with the 
manual as well: the bottom of (info "(emacs) Completion Styles") says:

   You can use different completion styles in different situations, by
setting the variable ‘completion-category-overrides’.  For example, the
default setting says to use only ‘basic’ and ‘substring’ completion for
buffer names.

Note the word "only".
