You are vastly overestimating what Freedesktop.org does.
Fd.o is a place to host shared specifications or their common
implementations. It does not (it cannot, really) mandate that anybody
actually use them; it was created because some people, 10+ years ago,
thought that some implementation details of different projects should
be communicated to other projects in the interest of interoperability.
The reason why those specifications ended up being used was that there
was enough buy-in from different projects already, in terms of overlap
A theme, in any tool kit, does not specify how the tool kit itself
behaves; that's part of the implementation, and a sound themeing
policy is to never let the implementation be accessible from the theme
(which is why GTK 2.x themes are terrible, as it forces developers to
write C code modules that inject themselves into the application's
process space). This means that you cannot really create a theme for,
say, GTK 3.x and then have it run exactly the same on every other tool
kit; it will require you to write a theme for every tool kit you have
installed on your system, in order to have them behave in similar
The idea to specify a theme for every tool kit that can be installed
on your system is a monumental effort and it will most likely end with
something that looks terrible everywhere and behaves differently — and
if you have any recent Linux installation you likely have installed:
* GTK 2.x
* GTK 3.x
* Qt 4.x
* Qt 5.x
and even if Qt5, Chrome, Firefox, and LibreOffice can use the GTK 3.x
foreign drawing API to at least *look* like GTK 3.x applications, this
still leaves out older versions of Qt and GTK itself — and it does not
solve the inherent issue of different behaviour.
The "consistency" argument has, effectively, "left the building" (if
it ever entered it) years ago; it's also vastly overrated when you
realize that all applications under Windows use slightly different
tool kits — even when written by Microsoft. This also applies to Apple
on their desktop. People continue to use both those platforms anyway.
Yes, there will always be people that wish for all their software to
be exactly the same and behave exactly the same; no, I don't think
it's an attainable goal — especially if all we can do is involved
freedesktop.org to write a theme spec.
