I'm afraid so (if subtly, though). gui_shell and system_manager are closed. Abovementioned directories contain the source for libraries required to write own applications... but not to modify/debug the behavior of these two.
E.g., I currently do not see a way to insert a menu item to create snapshots when arbitrary applications are running... or to add additional color options to the annotation menu. (remember that binaries on the M92 are statically compiled - and I fail to recognize a plugin interface, so far.
