The sorting does not take much:
-> size lib/qsort.o
text data bss dec hex filename
264 0 0 264 108 lib/qsort.o
The hashing on the other hand might be replacable.

Yes, this is one common use case.
But then, I see also systems that are running pretty complex shell
scripts to implement features like reliable software updates etc., and
there we see an improvment.
Also, speed is just one aspect - for me the capability of having
several "profiles" is much, much more important.
Best regards,
