Hi Jeroen,

I mostly lurk on this list, but I was struck by your combative tone.

To pick on two random bits:

Tomas’ tool chain isn't a blackbox, it has copious documentation (see [1]) 
and builds on any machine thanks to the provided docker container.

This is not to criticise your work which has its unique strengths, but to
state the obvious: these strengths are best discussed without passion 
based on factually accurate descriptions.
