I think most people aren't running jack without a gui and on an arm
computer.  In that situation debian, for instance, has its dbus
permissions completely hosed by default, from the standpoint of jack
anyway.  I had raspian working since last year, but a recent update made
my dbus hacks no longer work. 

Arch actually works out of the box with regards to dbus, although I had
some trouble giving jack realtime priority starting it from systemd.

Recently I built a test app using faust and writing directly to alsa. 
Super responsive, low latency.  Starts right up, no worries about -p256
or -p512 or etc.  I am building an instrument and I don't need the
flexibility of routing audio between applications.  I do need low
latency and reliability on startup.  Jack, while no doubt powerful in a
studio situation, is for me a needless complication which has produced
lots of sysadmin headaches and no benefits.
