In my opinion Bach's inventions or sinfonias contains many useful technical works but of course they sound great! I think to play Bach for technical work instead Hanon or Czerny is better.
In my youth I had to play some Czerny and Hanon. Don't think that it was very useful or more useful as good sounding "real" compositions. So I have the same opinion as you with Bach playing for developing the technique. One can combine doing something useful for the technique while playing great compositions that way
Indeed, the point is to make music, not just to push buttons in rapid succession. Of course, being an efficient technician is not a bad thing, it's just easy to lose musical sensitivity with purely physical practice.
