Since I too do not know which applications need this
axis-order-switching code, your solution sounds great.

No. When I comment out the axis-order code, it works perfectly well
for both WMS 1.1.0 and 1.3.0 versions.

The reason for this is that in 1.3.0 GeoServer already changes the
axis order in the input CRS and thus the calculated MathTransform is
already the transposition of x and y, i.e is the matrix

01
10

The MathTransform  code is in line 343 of
modules/plugin/imagemosaic-jdbc/src/main/java/org/geotools/gce/imagemosaic/jdbc/ImageMosaicJDBCReader.java

But this hold of cause only in my case. I'm too unfamilar with the
Axis-Order-Handling of GeoServer. Maybe someone else knows for sure?
