Yeah those both seem like glaring oversights.
Even though Gumshoe seems to only birth more Gumshoe games, that’s still interesting: a branch of the tree that is straight with no offshoots.
I've been told there's actually enough variance within games identified as "Gumshoe" that its more that the term is used fairly broadly (as I recall, I only own two (Mutant City Blues and Night's Black Agents) so its hard for me to tell.
