Engineering is responsible for deciding if the stairs are usable or not.
The wires are not capped and stowed for the purpose of using the stairs again in the future. If the wires are capped..... they will have to be re-terminated. Just adding an extra step to the process.
Pulling, capping, and labeling is a normal procedure for deactivation of systems.
The 737's entry stairs are a bitch to work on or find parts for..... if not absolutely needed..... they should remain inop.
