Every time I hear people say that physics has become has become a religion I want to stab myself. Every day, I sit at Peyton Hall at Princeton and discussions at the IAS where people are consistently debated. There is nothing dogmatic. If you are wrong, you will get corrected. See BICEP2.
"Bohmian mechanics has never been widely accepted in the mainstream of the physics community. Since it is not part of the standard physics curriculum, many physicists—probably the majority—are simply unfamiliar with the theory and how it works. Sometimes the theory is rejected without explicit discussion of reasons for rejection. One also finds objections that are based on simple misunderstandings; among these are claims that some no-go theorem, such as von Neumann's theorem, the Kochen-Specker theorem, or Bell's theorem, shows that the theory cannot work. Such objections will not be dealt with here, as the reply to them will be obvious to those who understand the theory. In what follows only objections that are not based on elementary misunderstandings will be discussed."
It's true that Bohmian mechanics has never been extended to a full QFT. But considering how little time has been spent on it, isn't it possible this is a result of observed bias against it, and not because it's fundamentally intractable?
For comparison, other theories that have ended up in more intractable places (such as string theory) seem to be considered mainstream.
