You missed:

Not really, no, for prefixed properties.

For example, WebKit has a policy of not changing the behavior of its 
prefixed properties once implemented, even if the spec then changes, as 
far as I can tell.

Then you probably don't want to be using prefixed things at all.  As 
things stand, you _do_ need to change your CSS whenever UA behavior 
changes (spec changes don't matter here except insofar as they cause UA 
behavior changes).
