Comment (by knarf):

 Actually - besides the good reasons already mentioned here, the gamma2
 shift evolution of BSSN_MoL can be almost achieved with McLachlan with
 suitable parameters, except a factor the lapse in the source of the shift.
 Thus, adding that factor (obviously steered by parameter) would 'solve'
 the specific issue of the gamma2 shift I had - but not other issues like
 ignoring ADMBase parameters for example.

 Also, in case it comes up: adding an 'if' clause to the code is either not
 an issue or an already existing problem, because the shift evolution does
 already contain one - for the switch between the 1+log and the harmonic
 shifts.
