Sorry Ben, but you are the one who sounds like a priest here, having 
invoked the "religious" qualifier twice in a row in this thread.

I think that Andy is asking absurdly good questions which are backed by 
candid logic and reasoning.  If anything, his arguments are purely 
technical and extremely practical. And so far all he's got for answers 
was rather subjective, emotionally charged and even dogmatic.

With regards to DT on ARM I'm rather "softly" convinced this is a good 
thing.  However seeing a persisting lack of truly technical answers to 
Andy's questions is rather disturbing, and makes me wish for much more 
than the current hype around DT which appears to fall flat when 
challenged.

There is one hard fact that no one can ignore: DT support on ARM still 
has a long way to go before it is truly usable.  The world just can't 
stop turning until this is ready.
