I suppose that having a configuration item to make notmuch do what it
does now if the default behaviour is changed isn't an enormous usability
reduction, but I still don't like it, and I would be very wary of assuming
that the necessary changes to the code will be as simple as it sounds.

I think that there will be lots of people (and organisations) who get
collections of email from elsewhere and want to add them all to their
own single collection for reference, archival, and research purposes.

So that those emails would be forced into the IMAP folder structure,
making them visible (and possible distracting) there when viewed with
a traditional mail client?

No, because that is part of its flexibility. Removing, or degrading,
notmuch's ability to access such files will mean that I may be looking
for a different solution to managing my email. That, of course, amy not
matter much to anyone else, but how many others will there be?
