Alexandre--I'm happy to put all this into an issue on the github, or
add it on to an existing one, if you think that would help.
I think this is still to vague for a github issue, but you can go ahead ;) let us just "try" to be more objective over there, and issues can get reissued so it's not a big deal to close one and start a new one from where the discussion led us to. It'd be nice to have more parallel discussions on this list as well.
cheers
