It doesn't, shouldn't, but many do.

The complaint in this sub-thread is that many times programs come with
bad default choices. Often, to compound the problem, there is no
uninstall. This is not about Unix, but people who write, manage, or
distribute programs. I used the term unix to refer to the community and
its culture, not the OS.

Here is the example a poster gave from his system. There may or may not
be other emacs related named files there, these are just the matches on
the *name* emacs:

   % find /usr -name emacs -print
   /usr/bin/emacs
   /usr/info/emacs
   /usr/libexec/emacs
   /usr/local/bin/emacs
   /usr/share/emacs
   /usr/share/info/emacs

To duplicate the convenience implied in your suggestion, one would have
to delete /usr.

To have package managers which work on only one or two sub-flavors or,
as in Fink's case, only on the software downloaded from one source is
really not such a hot solution (though a welcome "patch").

What is needed: 

(1) To change the culture, so that every program comes with a safe and
complete uninstall option. 

(2) To empower the user, so he/she can easily discover what a
particular file on his/her computer is for, and where are all the files
related to the package xyz. I think you want to be able to specify the
source (GNU or FSF), name (emacs), and version (27.5) with intelligent
defaults, like all versions when none is specified.

I haven't come across many programs with long descriptive file names.
However, I'll avoid this direction because I view it as less relevant.
I want precise and reliable tools to know what a file was for. I don't
want to guess such things from names.

The most simple solution to this would be to configure KDE to use
M-<ESC> for window switching. It's much easier to change things in one
place (KDE) than in several places (Emacs).
