This is true for 1.6, but not for 1.6.1 I guess.
And the fact that fsck checked too many bits was a bug, as it breaks
filesystems extentions designed to be backward compatible (by using
unused bits in the various structures, which are there specifically
for this purpose).

There is one problem left (PR 21283), which needs to be fixed before 2.0
