The WG considered this issue on 29 Jan and concluded that there is no
precedent for an objection to the spec on these grounds.

Well, the semantic constraint is there so that if an older processor
sees a newer version of the step, it won't silently do the wrong
thing. If you change the syntax, that can't happen so I don't think
it's an issue.
