>  If it was permissible to send MAX_STREAM_DATA x+4, no amount of reordering will make this a protocol violation

then you have to be able track infinite amount state because the peer controls MAX_STREAM_ID.

> If it was not permissible, and the remote peer just happened to open x+4 while the MAX_STREAM_DATA frame was in flight, then the peer got lucky this one time and the protocol violation won't be detected.

You can always get lucky, by it is sufficient to risk enforcement, and more importantly, it protects against tracking infinite state.
