I’d be OK with this change (if the compat impact is minimal). It’s certainly better than having two functions for each that only differed in whether they accepted a fill-rule parameter.

I’d also be OK with leaving fill-rule in the functions, even for properties that ignore it. I don’t find it that confusing or author-hostile. An optional parameter seems like a good fit to me for a sometimes-relevant value.
