Folder track behavior

Is there any particular reason some folders have less settings than others in Cubase 8.5 (e.g. Using the add inside folder option when adding a track/ using the add instrument rack option when adding an instrument)? These functions create folders that aren’t able to group edit, resize, mute, solo, record enable etc etc. I’m a bit lost as to why folders like that only exist when created that way but when done manually it’s different.

It used to be that Group, FX and Rack Instruments could only be created inside those special folders, and many people asked to have that changed. So now we have the option to not use those folders. For me they just got in the way.

It’s very weird. I litterally have no idea why there is even an option to create a rack intrument or a track instrument.
