CCS has the benefit of working well with three-phase power – which isn't used in North America. NACS doesn't support three-phase power but has a more convenient form factor.
Europe will probably stick to CCS Type 2 since three-phase power is commonly available at home.
CCS2 could certainly be redesigned to support 3 phase power in a smaller form factor if they upsized 2 of the power connectors on the mennekes plug to allow them to carry the dc current (similar to how nacs works). But it works well enough for Europe
