Oh, we've kind of forgot about this issue after merging https://github.com/kaitai-io/kaitai_struct_formats/pull/445. However, perhaps this issue should not be closed yet, because the current 3d/gltf_binary.ksy is to my taste unfinished and not very useful at this point - it merely parses one character string with JSON data and one byte array with binary data, without any attempt to provide a way of parsing the actual binary structures that are present in that byte block.

My proof of concept in https://github.com/kaitai-io/kaitai_struct_formats/pull/445#discussion_r598117321 can be used as a basis for creating a more in-depth KSY spec, which could then be considered more complete and usable out-of-the-box.
