Exactly. The order of reading .gitattributes from the working
directory or the index doesn't matter. The current mechanism
has a more fundamental deficiency.

Changes of.gitattributes can influence how the same content
is checked out to the work tree. If .gitattributes change the
checkout may need to be updated, even if the real content did
not change.
