What Then?

The thing is, "where it gets the job done" in my DMG bootrom example stands in contrast to what was brought up earlier. It's not the lowest level possible, but still achieves 100% accuracy. What I have issue with is saying that to make a completely accurate emulator, the lowest level of emulation must always be used. As an absolute statement, it's not true, but I agree with it as a general statement. But it isn't necessary in every case, just most cases. Going lower level definitely increases the chance of accuracy (given competent programming, documentation, and RE work) but it's possible to use HLE techniques in some situations even as you strive for "perfect" accuracy. When and where you can effectively use HLE like that depends of course.
