Are you serious?? What countries have patent claims like that? Never heard
of this issue...

If it were me I might be tempted to make this behavior controllable (with
the default to do your adjustment). It's feasible that a MUA could have a
different bug making the year be "00" (not just during the year 2000), so
the adjustment wouldn't be correcting the error, just changing it to be a
different one (which could lead to misleading bug reports on those MUAs).
Also someone might be doing something bizarre like OCR'ing in a bunch of
written correspondence (so they could throw away the hardcopies) and making
them into fake MH messages. That correspondence might extend before 1900.
I know, a pretty unlikely scenario (though, in a similar vein, if I were
moving files off of obsolete computer systems, I would want to use 'touch'
to restore their original dates, if whatever transfer protocol I was using
didn't do so).
Speaking of old years, if you wanted to, you could change your year 1969 to
1972, when email was invented.
