Yes, because the Emacs's upstream installation procedure installs
emacsclient in ${bindir}.  So "our "make install" wants to make sure
the desktop file will reference the correct emacsclient, not the one
found first on PATH.

My understanding is that you are asking this because some downstream
distro will find it more convenient for its users.  If so, why cannot
the distro modify the top-level Makefile.in according to what you
prefer?  There's no need to propagate distro-specific solutions to the
upstream project, is there?

Since different distros can have different needs and preferences, I'd
prefer not to make changes in the setup of the desktop files we
distribut in favor of one particular distro.  We distribute these
desktop files as a service to distros, and would not want to take
responsibility for understanding the needs of the various distros and
desktops, so as not to increase our maintenance burden in areas where
we have no real domain expertise.

Thanks.
