Actually, that isn't true. The data stored for pack-0.92 and 1.6/1.9 are
identical. Only the indexes change (and those are never copied as-is).

1.6 only introduces the "is stacking capable" flag, so has no on-disk
changes other than the format string.
1.9 introduces btree indexes, but again no major benefits for local
performance.
