Not necessarily.

The policy is completely up to the superproject (which is
git.git).  Currently, the policy is "make all" and "make
install" in git.git builds and installs what are considered core
parts of the system which includes git-gui and gitk.

gitk nor git-gui should not become useless without being in
git.git (iow, their build procedure better not depend on things
outside their subtree), but I do not think that is a hard
requirement either.  Shawn *chose* to keep git-gui buildable and
installable separately as well as as part of git.git.  Again I
think that policy is up to individual subprojects.
