Because you are executing programs that you don't control (what if
trying a sort.exe causes a crash or any other kind of problem), and
because probably it'd fail if I happen to modify the PATH afterwards.
If I have to manually configure a variable and after a while I change
the path I'm more prone to remember it that if Emacs somehow configured
it behind my back.

Sure. But we already have cases like these now, and they're resolved by
having -program variables. The first "find.exe" in my PATH is
C:\WINNT\system32\find.exe. Same for ftp and telnet. Ange-FTP didn't try
to find what was the "right" ftp, I manually configured

Having good defaults helps here.
