There is not mistake. Each way has advantages and disadvantages. As for me - when i work with pro audio software, i don't like to lost jack-less applications, like web browser. For most software, which may, there are default settings to use jack - i.e., audacious, vlc, and kde sound system has jack backend at highest priority. As for switch between firewire / alsa - it could be done easily, as simple as lash_button (but checkbox and written with python... probably, even as some applet).
Btw, latest version of jack2-simple-config in KXStudio has own configurator, which can change settings on the fly, but when i changed backend between dummy and alsa (firewire - did not use yet), changes take effect only when i stop and start jack later (oh, studio). Also it is nice, to have some effects host (ingen or some rack) for output. I.e., i have ladish project with jack-rack (with Plate Reverb Stero) and musescore, because freeverb, used in fluidsynth, as much as all other convolver-based reverbs, can't give good results for short reverbs (in JR i muted long reverb, that sounds like reall hall). Since freeverb has only one very long impulse, it just truncates it for short reverbs, producing awful result (more like resonance of huge metallic list, that reverb).
