Yes, that is pretty much intentional.  Having a link for higher
layer tools can use (i.e. tree objects can contain 160000 mode
"gitlinks" to subproject commit objects) while not considering
such linkage part of the reachability is the whole point of
plumbing level subproject support.  It allows people not to
download repositories of uninteresting subprojects.  Higher
layer tools such as clone/checkout/diff could be instructed
(currently they cannot be, though) to recurse into subproject
directories if the user wants to.

A few good pointers for this topic are:
