Eg. I have a router sharing wifi for 'work' with a permanently maintained vpn connection to the workplace intranet. Another sharing wifi as 'Australia' that I connect to whenever I want to watch TV from Australia with a VPN to an Australian server and lastly the standard home Internet wifi.
It's super easy to do if you have a couple of old wifi routers and even cheap home ones seem to have some VPN support these days. A big advantage, aside from centralizing the VPN setup so you don't screw it up is that it's trivial to connect any device to the VPN. Just join the relevant wifi address! Boom I'm now in a VPN to Australia from any device without messing around setting up that device specifically because I connected to the 'Australia' wifi.
I do this with multiple old routers but I actually think there's probably a market for a single home router that vpns to multiple locations in the world with a different wifi network for each of those just for the sake of easily having your TV/Roku/iPad appearing to be from somewhere else trivially.
