That's, more or less, what /opt is supposed to be. QT and KDE used to be "integrated" that way, until distros finally got around to put them into /usr. So, there really is a standardize mechanisms with those uncommunicative packages in the FHS. (Note that the Unix family as a whole does not standardize filesystem layout, even though Solaris also has /opt and uses it for exotic packages such as GNU gcc).
