In the Spheroid case, it has no negative impact.

In the Datum case, the only impact is that CRS.equalsIgnoreMetadata(...) with a
Oracle and a non-Oracle CRS will returns 'false'

In order to get up to the point we can create CRS objects from WKT, yes. For the
CRS.equalsIgnoreMetadata(...) issue, we may additionnaly add entries in the
DatumAliases.txt file.

Could be done using hints... I realize that it may not sound like an appealing
solution to everyone.
