All versions of the DWARF spec have support for vendor-specific extensions. I don't see the advantage of allocating one of those and communicating it to other compiler writers (to avoid them using that same extension for something else) instead of submitting it for inclusion in the official DWARF standard though. Such things should only be used in cases where there is no chance of ever getting it included in the standard.
