That kind of depends on the intended consumer, what it's actually used for, etc. If this is prototyping a way to solve the ICF confusion within debuggers, to be consumed by LLDB, with an eye toward making an actual DWARF proposal, then the LLVM vendor seems appropriate. If this is for some secret tooling within Meta, then META would be most appropriate.
