Hmm. And I guess postfix/sendmail/exim4/ssmtp would be another, so I see your point. However, with my distro, I can trivially easily switch back and forth between MTA/MUA's, in fact, I just switched between a bunch of them that last week.
Jack/Ardour's allergy to distributions in general (and Debian in particular) has made this harder to manage. If I could go "sudo apt-get install jack-flavor-of-the-month" and it switches over, then go "sudo apt-get install jackd-original" to switch back, then it's no problemo. 
There are also other servers/services like Apache/Nginx/thttpd/lighthttpd, which *can* coexist or even all run simultaneously on a single machine. That might be another model for making the various jacks easier to switch between. I remember some discussion of this many months or years ago, but I don't know how that turned out.
