Because it sets precedence. This way tools will expect the prefix on Linux.

And then someone will push the topic again and Qt fails to "see  it"
again, thus delayed to Qt 8.

Come on Kai, please realize it is **not** a new issue. In fact I
pushed this exact thing **two** years ago and then insisted on it
exactly to avoid this resolution.

If you (Qt company) do not really like it, then go ahead and say"we
don't care about distributions". Or just bite the bullet and do the
right thing: get those binaries renamed (or a method to do it).
