I have a circuit breaker in my master panel that serves a
disconnected/unused circuit.
I don't just want to remove the breaker because that would leave a
gaping hole in the panel.
Can I just disconnect the wires from the circuit breaker and put a
wire-nut on the end of each wire? Is it ok to have some lose wires,
terminated by wire nuts, dangling in the panel?

Why not just remove all the unused wires etc and leave only the circuit
breaker?
