That's achievable by a few lines of text:

   Linux distributors are strongly advised to install all Qt 5 related executables
   (qmake, uic, rcc, ...) with unmodified names to a directory that is not 
   in $PATH and set up symlinks  'qmake5' etc that are in $PATH.

   Linux distributors are strongly advised to install all Qt 4 related executables
   (qmake, uic, rcc, ...) with unmodified names to a _different_ directory 
   that is not  in $PATH and set up symlinks  'qmake4' etc that are in $PATH.

   If Linux distributors feel strong about it, they may use their distributions
   "native" system to handle alternatives to set up  'qmake' etc links in the 
   path to point to the qmake binary in either  the Qt 4 or the Qt 5 binaries 
   directory,  [Suggesting to modify PATH is probably the saner choice, 
   I don't really care about this part]

User support could then be:

  "write qmake5 to build Qt 5 things"

Users/Admins could then use the distribution's "defaults" system to 
switch the "system" Qt version, they can also override the system
setup by modifying their local PATH settings, per-shell even.

None of these operations are "unusual", or "technically challenging",
or "cumbersome", and it does not require, or even only benefit, from the 
proposed renaming of the binaries.
