Is that a real concern for even 0.05% of the population? I'm sure Apple will have a workaround.One of my concerns about portless is that DFU mode may not be possible. When the whole OS is bonkers, including the network stack, today you can put into DFU mode and connect via lightning to a desktop and restore.
The lack of a port on the apple watch is likely why you have to send your watch to Apple just to downgrade watchOS.
I may not have all the terms right, but that is the gist.
