@alzhao Okay. Thanks!
My concern was that if —somehow— it ‘broke’ the default web GUI, then my only “get well” option would be a full RESET of the firmware.
…which, as you know, would result in quite a bit of time getting the router re-setup how I like it.
(I am presuming that the changed ifnames would cause issues with trying to reinstantiate the old backup of the config file…)

Am I understanding the consiequences of “it didn’t work out well” correctly?

Thanks again, sir!
