I've got a ton of mason bee tubes. They are awesome.
To use a silicon valley analogy, nobody has figured out how to scale out mason bees. Not to the > 200sq miles of pomegranates, pistachios, and almonds owned by the Resnicks. The Resnicks funded some in-house research and apparently considred it a failure.
It's probably possible. Might not even be hard once you know the trick, but it's certainly not a slam-dunk.
