Correction, the transmissibility calculations naturally *also* become simpler when the Euclidian norms of the normal vectors equal the corresponding interface areas.

Having normals whose (Euclidian) norm equals the corresponding interface area means that the formulae for (mimetic) inner products become simpler. See function mim_ip_simple_all() in opm/core/pressure/mimetic/mimetic.c for details. In the context of opm-core, those are the only *consumers* of (detailed) face normal data. I don't particularly care either way, but changes will be needed on one side or the other to reconcile the views.
