Thankfully, you're now switching to RequiredComponents for the session components, that is a good move.
But you're still claiming to be GNOME when it comes to autostart, and blacklist GNOME apps that use this id, since you don't want them running in Cinnamon. The autostart spec is problematic to begin with (mainly the *ShowIn stuff, which was problematic from the start), but this is just subverting the spec to the point where it becomes entirely useless.
What is keeping you from using a proper identification, X-Cinnamon, or even Cinnamon for autostart ? I really don't see what you gain from this false identity.
