IIUC the problem you see is not that the sequence is echoed but that the
echo area is cleared at an inopportune moment.

I don't see any reason off-hand to oppose such an option, but someone
will first have to figure out exactly which part of the code is
responsible for this clearing of the echo area.

Maybe it's just a plain bug because some part of the code didn't take
into account the possibility to rewrite a key sequence to the
empty sequence.
