Re: [csswg-drafts] [css-properties-values-api] `@property` descriptors should be optional whenever possible (#13211)

Not being able to create guaranteed invalid values with registered custom props is also why it is impossible to create a transpiler for `@function`. So definitely would have been useful to have this, I suspect it will still be useful in the future.
