The bubble sort vs. quicksort would be an incorrect analogy. The idea here is to inject several optimized versions of the same code. My arguing was that one generic version might perform better than a multitude of specialized copies of the same code.

Yes. Especially as today's CPUs move towards annotating cache lines and doing certain optimizations of the generic functions by observing their usage and annotating specific instructions. Creating _more_ code goes into the opposite direction.
