I would find less GDB options to be good.

This is not completely correct:
  if (version < 6 && !use_deprecated_index_sections)
  if (version > 7)

So version 6 is not "current" but it is still used even without
-use-deprecated-index-sections.  At least gdb doc should be exact IMO.

It is also questionable if version 6 should be ignored without
-use-deprecated-index-sections.   I guess the possible performance regression
(against non-index case) is so rare it was not worth ignoring version 6.
