How do you prevent loopholes based on industry classification and job switching? Ex. what's going to stop a company from hiring a lower-minimum "design" worker and then having them do 10% design and 90% writing code? We have to assume that companies will attempt to abuse the system any way they can, so a simpler blanket setup for everyone is going to be much more effective than attempting a nuanced setup that would require even more oversight.

As others have pointed out, it would be better to create separate visas with stricter limits for industries that really need them, like high-level interpreters.
