I wouldn't say I am opposed to that (I don't consider myself a decision maker here), but emitting a (non-standard!) form that gdb doesn't understand doesn't sound that much better than not emitting anything. It might be different if we went to gdb and asked them to implement it, but I don't think anyone's planning to do that.

I guess my preferred solution would be to emit the standard form for gdb tuning, and use the non-standard thing for lldb (assuming it doesn't break gdb catastrophically), and also start using lldb tuning for Google. I don't know how hard the last part would be, but I can try to find out.

Anyway, I think I've said enough now. Let's see what others have to say to all of that. :)
