No, -gdwarf-3 is the default.  Someday it will be -gdwarf-4.  -gdwarf-2
really is obsolete, DWARF 2 is quite ancient and there have been many
important additions since then.

-gstabs+ ... I don't know as much about stabs.  My impression is that
they don't handle C++ very well.  Certainly on the GCC side nobody puts
any work into them at all, and very little work in GDB.

So, I think that sentence remains true.  Perhaps it is untrue on
platforms which are themselves obsolete.

Eli> Why is this part important to a GDB user?

A previous sentence mentions that the information is large.  Assuming
that this earlier sentence provides any value to the GDB user,
mentioning that the problem can be ameliorated also seems appropriate.

Yes.
