Revision walking is not the only gate to access objects. Others like
diff machinery needs also be taught about rev-list limits.

Right, good point.  Are there others than the diff machinery (and the
fsck special case) that you know of?

A lot (just found out as I was pushing subtree clone as far as I
could). For merging, you can hardly limit sha1 access. When writing
tree, git's particularly paranoid and check for sha1 existence
(has_sha1_file and assert_sha1_type). You can find that has_sha1_file
is used in many places, not just commit/write-tree.

Narrow/Sparse/Subtree/Lazy/Whatever-it-is clone will have hard time..
Oh.. the lazy one does not.
