Yes, I though that too. But it would work only if 1) Only one set of
Bursa Wolf parameters exist for a given Datum and 2) It was always
specified. But neither are true.
Actually, CRS.equalsIgnoreMetadata(...) ignores the BursaWolfParameters
because they are too unreliable for CRS comparaisons; the Datum names
are more reliable, while imperfect.

I though that they where already there, but maybe not. I will look at it
and add it if needed.
