In practice they will probably always have to be connected to, or through, software. Your servo power is controlled by the software and you cannot cut it directly. Definitely the limit switch which is used as the home switch works through the software and you want it set up so that you can run over the switch and then back off to set the home position. In the opposite direction if you are running servoes and encoders mechanical limit switches may be unneccessary because you can have soft limits in the form of maximum allowable encoder counts. This way your software can predict that a move will exceed the limit and not even start.
