I do agree. Probably no one else will want/need this in DWARF except us as I don't believe anyone else is re-creating compiler types with DWARF. Not that I don't think it is a good idea for debuggers to do as it allows the compiler to be used in the debugger. That being said, we should probably look for solutions that are better for all DWARF clients or just fix things in our debugger.
