I understand Drepper pretty much considers string.h a lost cause, and I can’t fault him for that.
It’s rather that POSIX decided to add the strl functions, so adding them (and verifying their semantics) is a necessity.
A purist would support removing strcpy, etc... but that wouldn't go well, so adding an improvement is acceptable.

That is very much Drepper’s position:
> Correct string handling means that you always know how long your strings are and therefore you can you memcpy (instead of strcpy).
> Beside, those who are using strcat or variants deserved to be punished.
They should have added a warning for strcpy 20 years ago and shipped the compiler with it default enabled.
