[CQ-Contest] WW-Digi Contest -- Rule Clarification

Is this really an issue? The FTx bandwidth is a fraction of most
modes. So if there are multiple streams per instance, the occupied BW
is still pretty minimal. And contest results are going to be compared
to like - meaning CW scores and SSB scores - currently limited to one
signal per band per time.
I'm not a FTx fanboy, but it seems this is a lot of worry about
something that is unlikely to occupy a net bandwidth even remotely close
to what a serious CW contest has.
Maybe I'm missing the point of worry?
