Yes. However, Unix has evolved in 40 years, sometimes in a good
way, sometimes in a not so good way. And piling on more functionality
into su wasn't exactly the best idea: from a simple privilege-gaining
tool, it mutated into something between what it was and a complete
login - it lost the clarity of concept it had at first.

Oh, I'm not blaming some abstract entity called "su". When I say that
su is not good (anymore), it's obviously on us.
There's a reason why I have written programs performing privilege gain
without bit s executables. ;)
