Intent is something difficult to work out. I suspect many just hit
mutt's equivalent of the "g" key. Getting upset about it is the road
to a flame war.

Indeed.

Or, could we consider the BTS? Not Cc'ing a bug report submitter in a
reply runs a very high risk of leaving them out of the loop.

Definitely (whether they are known to subscribe or not).

Which brings us back to - how does one know someone is subscribed to a
Debian mailing list?

Seeking out is time-consuming. A recipe for automation is given in
another post. It gives you everything you want.

I've tried to point to some of them.

(Transmission headers are not unimportant. You cannot have it both
ways; it's either a duplicate or it's not).

It's probably impossible. Determining a duplicate email solely on the
basis of an identical Message-Id: is a brain-dead idea.
