Well, the "eval feature" is used extensively at many places, yes.

If you mean "use `eval' even for trivial expressions composed of nothing
more than a symbol", I've used it as a poor man's buffer-local faces
a few times.  But admittedly, it's only rarely used.

Right, I think if variables had names like `font-lock-foo-face' while their
content was `font-lock-foo' it would have helped a bit.

Another way to avoid the confusion would have been to introduce a whole new
self-evaluating datatype for faces rather than use symbols.
