Why do you think this? - Pincontrol handles can be obtained at runtime. - Pincontrol states can be changed at runtime. The fact that a the handle is retrived by the device core and set to the states named "init" or "default" during boot is just a convenience. You can have as many and as fine-grained states as you want. They can pertain to just one pin too.
