I'm not aware of any significant use of -g1. It is very rare for
anyone
to mention it in a bug report for instance. Once upon a time (before 2002-03-19), it was used for compiling libgcc, but that was just to ensure that it got tested somewhere. From my Cisco experience, I
would
agree that backtraces without line numbers are not very useful. It would be OK with me if these changes were added to -g1 instead of creating a new -gmlt option.

Is anyone still working on this? It would be very useful to include this option in gcc trunk, and have either -g1 or -gmlt emit line number information. This saves considerable space and time during compilation for large builds where full debug info is not needed, but line numbers in stack traces are still helpful (e.g. regression testing opt builds) If I can help somehow, please let me know how.
