How about using a GNU/Linux distribution that does not ship a 2 1/2 year
old versions of jackd?

Yes, you can change the audio system any time, also while a session is
loaded.   Ardour-Menu > Window > Audio/Midi Setup

No drawbacks. Except you'll have to stop jackd if you want to use the
same device as jackd is using.

There's also a "None (Dummy)" audio system which does not need an actual
device, but this only available if Ardour was configured
with
    ./waf configure --with-backends=jack,alsa,dummy

(Ardour4 debug builds from http://nightly.ardour.org/ have this enabled).
