I think there could be value in adding CSSHPB with new code inside GDAL NITF. See https://github.com/OSGeo/gdal/blob/master/gdal/frmts/nitf/nitfdes.c#L209
Do GLAS/GFM later.

How are Data Extension Segments (DES) accessed > through GDAL? Complicated topic. TRE stored in DES are reported in the TRE and xml:TRE metadata domains. For generic DES extraction, you need to build GDAL with the ESRI_BUILD macro enabled, and then they should be reported as Base64 encoded content in the NITF_DES metadata domain, but I haven't tried such builds recently.
