1. I want the name to be opaque and semantic.
2. I also want a pre-defined set of faces for highlighting apart from
the one "core" highlight face. I think there are 9 hi-* faces and
these numbers are good enough.
Think of them as extra colors in my palette.
Having a set of highlighting faces will help in theming. For
example, consider finding file in ido-mode. When I do C-x C-f, I see
various faces - the minibuffer prompt, ido-first-match, ido-subdir,
ido-indicator all occurring /next/ to each other. If there are
hi-lock-N faces, chosen by a theme designed, one can simply have ido
faces inherit from these themed faces. It is much cleaner.
Remember choosing faces that can co-exist in buffer without much
trouble to eyes is challenging task - one needs to balance harmony
and contrast. A theme designer is likely to work with a palette and
can go with color-picking techniques like triad, tetrad schemes. See

Triad and tetrads apparently are colors that are 120 and 90 degrees
apart in the color wheel. So if there are N highlighting faces, they
can be spaced 360/N degree apart in a color wheeel.
Drew's reasoning that it is the N-th highlighting face in a sequence.
3. Configuring an yellow face in red is a bit ugly. It is declaring a
variable name FALSE that is assigned a variable value true.

While reading a face name from minibuffer, if the face name itself is
highlighted in that face - think rainbow mode - then the name of the
face shouldn't matter.
What you are asking for is a constant face whose properties don't change
at all. One can have an elpa packages which provides constant faces,
that are immediately useful.
