Check if CGCS2000 and WGS-84 are equivalent for the caller's precision.
CGCS2000 and WGS-84 share virtually identical ellipsoid parameters.
The difference is sub-centimetre level (< 0.11 mm at epoch 2000.0).
For engineering-grade accuracy (> 1 cm), they are interchangeable.
This function returns true, indicating the identity transform is valid.
For geodetic-survey-grade work (mm-level), users should apply an
epoch-dependent tectonic plate motion model — this is outside the
scope of a browser-based library.
