[css-animations-2] Should `animation-delay-end` be added to `animation`?

[cdoublev]

I could not find any issue/comment related to this:

[Issue 4] Should animation-delay-end be added to the animation shorthand?

https://drafts.csswg.org/css-animations-2/#animation-delay-end

What are the reasons for not adding it?

Thanks for opening, it was on my list (:
There's no reason why not, question is how?
I suppose it should be something like the 3rd <time> becomes the animation-delay-end.

Yeah, the reason for not would purely be the complexity of the shorthand.
