In general, I agree that messing with random settings is not a great idea. But these particular settings are some that I would feel pretty confident messing with. Like setting a different 5Ghz network name is done for a particular reason, because you want to be able to choose 5Ghz or 2.4GHz for the connection, and you don't want it to switch back and forth as it wishes.

It seems that the autoswitching has gotten good enough to trust that it's making better decisions than you are about whether the 5GHz network is superior.
