Changing VST Instrument alters order on Rack

Is there any reason that this should happen, i.e. why can not the instrument be changed without changing its’ order in the VST Rack?

In other words “changing” a VST Instrument on the rack merely removes it from the list along with all of its’ outputs and re-instances a new plugin, which is not really the behavior I’d hope for or expect.

For example, in VEP I can re-order instruments in Cubase I cannot.
