How does this help in your scenario ?
How would your launcher get to know what path to use ?

Potentially problematic if plugins might install a qt.conf that isn't
what your application needs.

Why isn't this first ?
I would generally expect an environment variable to take precedence over
all other configuration options except command-line options.
