I suspect it will not come as a surprise that I really dislike the
implementation proposed here. I will not repeat my arguments, I have
done so on several occasions already.

Anyway, I didn't go as far as to nak it even though I _strongly_ believe
this debugging feature will add a maintenance overhead for a very long
time. I can live with all the downsides of the proposed implementation
_as long as_ there is a wider agreement from the MM community as this is
where the maintenance cost will be payed. So far I have not seen (m)any
acks by MM developers so aiming into the next merge window is more than
little rushed.
