OK, let's consider this. There are three cases:

1. A new program gets installed with the same name as an existing one,
   in the same directory.

2. A new program gets installed with the same name, but in a different
   directory in $PATH (and before the existing one).

3. A new program gets installed with a new name.

(I'm putting aside the program deletion case.)

You're saying that the seond scenario is most common, and common enough
that we should develop a complex solution for it? I'd have to see more
data before I'd accept that.
