That was the direction I initially wanted to take with this
out-of-tree build work. I'm not saying we must absolutely stick to
this initial direction, just stating what my initial intention was.
I really like when things are consistent, and so for me this
out-of-tree thing had to be an all or nothing thing. But maybe I'm too
psychorigid :-)
