In certain groups the desire is to keep threads intact. So when a
followup comes in the article(s) in the reference header, and the
followup itself, are saved in tradspool. When the most recent article in
the thread is N days old the entire thread is removed. Or at least such
is the desire.

Yes, that's the whole intent.

Even that's not clear, since these are articles identified after
(sometimes long after) the original post. The possibility of a change of
message-id was discussed internally, and discarded as leading to

Not optimal, but certainly not a huge hit on space. These are infrequent
enough to allow for some tradeoff between ease of implementation and
losing a few bytes.

Doesn't matter, and the overall volume is too high to make tradspool
attractive. Overhead for the exceptions will not be an issue, overhead
for the general case will really hurt.
Thanks all for your thoughts, I will think on this for a bit. I'd like a
clean solution, since that might prove useful for other things as well.
