This seems like a fairly trivial and useful addition, but can we put
this behind a feature flag? It's not hard to imagine some code looking
at `CSSKeyframesRule.length` as a proxy for "is not Chrome" and
something going wrong (though, I imagine this is a very small risk).

Anticipated spec changes
Open questions about a feature may be a source of future web compat or
interop issues. Please list open issues (e.g. links to known github
issues in the project for the feature specification) whose resolution
may introduce web compat/interop risk (e.g., changing to naming or
structure of the API in a non-backward-compatible way).
