Why not ?
If the mail buffer is not yet displayed, it would behave just like it does
now.  And the mail buffer is already displayed somewhere, it would select
that window instead of switching the current window to show the mail buffer
a second time.
Sounds like an improvement to me,

PS: BTW, the behavior I describe is already the behavior you get if you
    use (add-to-list 'special-display-regexps '("foo" (same-window . t)))
    instead of setting same-window-regexps.
