The Keyframes section of the CSS Animations Level 2 spec discusses how animation-timing-function applied to individual keyframes should be account for along with the offset to merge keyframes with similar offset and easing.

Should animation-composition also be accounted for here such that only keyframes with the same offset, canonical timing function and composite operation be merged?

I have WPT coverage in progress in graouts/wpt@3343e4f if anyone is curious as to what this would look like in practice.

I think that makes sense.
