Why should what the hvc driver support have any effect on
what the binding should be?

And anyways, both the boot wrapper and udbg (and hence early
debug console) have totally indepenedent functions for
reading and writing.  

And for that matter, we also support output on monitor and
input on keyboard for linear frame buffer on 6xx via the
btext output (but only adb input).
