I think as "features" go, using regression tests makes a lot of sense.
I think it's important for "features" to be something trustable and
generated completely automatically.

Emacs uses `featurep' (which is more or less like "is package <foo>
loaded?") and `fboundp' (does function <foo> exist), but it never feels
very satisfactory and is quirky.
