I've been using my Thinkpad that only charges over usb-c for 5 years now and the port is still like it was new. Can't see why this is an issuse, especially that I used to have issues with some barrel port chargers and needed to replace them. On a contrary I now have charger with a plugin so simple that it's unlikely it will break anytime soon and finding replacement charger is super easy as it is FINALLY a single standard port. I actually have 2 such chargers because of SteamDeck and they both work with both devices. Even if the connector in my laptop broke, there's second one that I only used few times + replacing it would be easier as it's not a big deal to find fairly standard connector to be resoldered, and with older laptop chargers there are many different variants of proprietary connectors.
