We cannot. From my original mail:
--------------
CRS.transform(mathTransform, envelope)
This method is fine for a class of transformations, such as affine
transforms
(extensively used to apply grid to world transforms in rasters) and
flattening
transforms (going from a 3d to a 2d envelpe), ....
---------------
The best we could do is to to add javadoc telling people not to use it for
a CRS transform...
if it wasn't that it's already there:
* Note that this method can not handle the case where the envelope
contains the North or
* South pole, or when it cross the ±180° longitude, because
{@linkplain MathTransform
* math transforms} do not carry suffisient informations. For a more
robust envelope
* transformation, use {@link #transform(CoordinateOperation,
Envelope)} instead.
