Yeah, you're right.  Sending side should not have any issues like that.

My receiving end (I think fetchmail slurps from my ISP and drops mails in
my local mbox, but it's a long time ago I configured my system...) does
quote only the "From " at the beginning, which is consistent with the
traditional mbox behaviour, so I see one, one, two, three in my local
mbox, and zero, one, two, three on gmane news article.

If this additional option claims to produce a mbox, I think:

 (1) quoting only /^From / (not /^>*From/) to be consistent with the
     standard practice is the right thing to do; and

 (2) reading side might need to also pay attention to /^>From /, in case
     somebody feeds an output from this option back to send-email.

However, strictly speaking,(2) may break the standard workflow of
generating patches with format-patch and feeding the result to send-email,
as format-patch does not do /^From / munging (and it shouldn't).  The
issue is mostly theoretical --- it only matters if your commit log has a
line that begins with ">From ", and people who have worked with e-mail for
any nontrivial period have already learned to reword their sentences to
avoid lines that begin with "From " (or ">From ", for that matter) anyway.
