Funny thing is that session change timers don’t seem to matter when you switch between ships. You can just hop between as many as you can possibly click while the 10 seconds ST runs after the previous ship change.
The most important ST that should go is the one after docking. It is useless. You are either docked and see your hangars and can change ships or you are not docked and cannot see and do either. And to check if you really changed a ship while docked, you have the ST after said ship switch before you can undock. The ST after docking that prevents you from doing anything is so annoying.
Alternatively I think this would help, too:
