Sorry for the multiposts: a big reason I'm opposed to `steps()` as a name is exemplified perfectly by the final paragraph of <https://github.com/w3c/csswg-drafts/issues/1371#issue-228525559>:

> From a programming perspective all the graph examples should have a N value of 4 and a option describing the range, e.g. from top left: steps(4, openclosed), steps(4, closedopen), steps(4, open), steps(4, closed), but I know that would make no sense to a lot of designers.

The logic here is that all of them have four "steps", in the sense of distinct values that show up in the graph.  This understanding is encouraged by the name. But it doesn't match user expectation in any way - the animation has 2, 3, or 4 visible values expressed during the animation's duration, and so should be expressed with an argument of `2`, `3`, or `4`.  A name that is instead focused on the values themselves is a little better - I think `frames()` does this reasonably well, and would want something with a similar framing if we don't use `frames()` itself.
