I find the opposite Art. I've found that the self imposed constraints of equipment, format/size, print medium, etc have enabled me to go much deeper, much faster. I used to constantly dabble and experiment with new things - a new paper or a new toner, maybe lith, enlarging one day and contact printing the next. As a result I confused myself, mastered nothing, and was creatively boring. As soon as I decided to constrain myself I started making real progress. That says much more about how my mind works than about technology or process of course.
What I do find incredibly attractive about hybrid is that when I need to I can make a digital negative for contact printing. I've no plans to stop using film - using a view camera is completely different from using a smaller format, and I very much prefer film negatives to digital ones. But sometimes LF is not the answer. I did a project with a dancer recently - lots of spinning and jumping - almost impossible to work productively with 10x8 (though if we'd had infinite time and money we could have worked this way - as witnessed by some of the prints I posted in APUG a while back). But by using digital capture we built two really good portfolios over a few shoots, and now I'm slowly working through creating decent digital negatives so they can be printed. And when I'm travelling it's much easier to carry a rangefinder and a few rolls of Delta 3200 - develop, scan, print a digital negative, make a platinum print - perfect. I really like the grain from Delta 3200 in Rodinal printed with platinum - yummy!
So for me it's not a creativity enhancer, it's just another tool in the toolbox. But as Thomas said in another thread, "To each their own, I suppose."
