 from CH1903 - I have no idea how much or if the differences are big enough
 to be relevant.

 > 2) I didn't have any test points to verify the parameters - in
 particular we always need to check the sign of the 3 rotation parameters
 (the 4th, 5th and 6th numbers out of the 7) as the American/European
 conventions are different.

 > If somebody can verify these two points then we can uncomment the
 parameters.

 I cannot varify it (maybe someone in grass-dev/user ML), but I would vote
 for uncomment the parameters and close the ticket (or to postpone it for
 6.4).
