Probably you remember of Frank's tutorial at https://trac.osgeo.org/gdal/wiki/UserDocs/RasterProcTutorial See the "Virtual files" section towards the end. Thinking just out loud: some Python script using gdal.Warp() API to deal with antimeridian could be a useful contribution to the project Like start with a raster in UTM 60 / UTM 1 crossing the antimeridian and produce 2 geotiffs in EPSG:4326 / EPSG:3857 with the east and west parts.
