I don't know, does the KISS (keep it simple, stupid) principle not apply to home brewing?
I suspect that most use a PID to have precise control over mash temps, then just go with another one for the boil. Manual mode on the PID gives you the same control (with a digital interface rather than a mechanical dial), and you have the additional ability to set boil temp around 208F, walk away until the alarm sounds, then dial in the boil while attending for boilovers.
Absolutely nothing wrong with the simple approach you describe, though.
