Every single configuration-reading program will have to read user
configuration in two different places, move existing configuration
files so that it is clear to users which configuration file will take
precedence, and then at some point in the future, stop reading
configuration files in the old location.

Complicate this by the fact that many people keep their home
directories in version control systems[1] and otherwise modify
existing behavior, and that for some of these programs, the
configuration can lead to inaccessible or nearly unusable systems.

I would imagine that we're talking about at least an hours worth of
work for every single program, with some serious additional design
work on top to deal with other problems which I haven't foreseen in
the brief period I spent writing this mail. All for little benefit.

Quite the contrary; they *love* collateral damage. If they can make
you miserable enough, maybe you'll stop using email entirely. Once
enough people do that, then there'll be no legitimate reason left for
anyone to run an SMTP server, and the spam problem will be solved.
