It's all too easy to say, as a reader (whether you're a page author or an implementor), "Hmmm, what's the syntax of 'animation-timing-function' again?  Let me Google.  Okay, here it is."  And there's no indication of 'initial' or 'inherit' as possible values.  Even if you heard one time that those values are supposed to be accepted by all properties and remember that fact, in the effort to understand the actual syntax of the property it's easy to let the "universal" keywords slip your mind.

 It does seem to me that we should at least add "initial" to the blanket statement, like this:

# All properties defined in this specification also accept the 'inherit' and 'initial' keywords (individually) as their value, but for readability it has not been listed explicitly.


Beyond that, I'm not so sure having universal values slip the mind is really that great a concern. How many times does a person need to be reminded before they just accept that they are truly universal unless noted otherwise? The statement at the top seems enough, since search engines don't usually link to anchors within the page. Maybe the heading could be "Values and Universal Values" so that you are reminded in the table of contents at the very top, but that sounds a little weird.
