You don't really propose putting all of that stuff in *Completions*, do you?

When it comes to display of color and such, people have very different needs
and preferences. Of the two screenshots I sent, I prefer the one with the
face on the entire face name; some other users might prefer the one with the
swatch; still others will prefer to see just the names, with no WYSIWYG

Allowing for different user preferences in a reasonable way is not violating
Occam's razor. We can discuss whether "a dozen of new representations of
face samples" is needed, or whether a few (as I proposed) suffices. That is,
we can discuss what constitutes "unnecessary multiplication of things" in
this particular case.

It is violating Occam's razor to multiply things unnecessarily in
*Completions*, under the arguments of (a) code reuse or (b) user
familiarity. The swatch screenshot I sent provides everything that the
`list-faces-display' provides, without all of the unnecessary clutter, and
it lets users control the size of the swatch.
