outermost-only-face-count in rainbow-delimiters

I am using rainbow-delimiters.  Does anyone understand how outermost-only-face-count
functions?

I suggest you set it to (- rainbow-delimiters-max-face-count 1) and
insert a bunch of parens: ((((((((((((((())))))))))))))) and see what
you get, then try with (- rainbow-delimiters-max-face-count 2).

This limits the rainbow faces used for cycing to the last 1, the last 2
faces, etc, for paren levels deeper than
`rainbow-delimiters-max-face-count'.

Took me some time to see through this.  Is there any particular use for it?

I have no clue.

I do not see a valuable use for it except as an interesting complication.

You do not have to understand every option in every package you use.
Just keep it at default.

If I understand the docstring correctly, you could set the option to 1
and then the first face would only ever be used for top-level forms,
never for some deeply nested forms. Sounds like a handy feature if you
are into that kind of thing.

(Disclaimer: I do not use rainbow-delimiters.)

It seems to be the other way round: the face is only used for all deeply
nested parens, and the outermost `rainbow-delimiters-max-face-count'
parens are unaffected.
