Yes if you want to. Routers are a necessary abstraction from the IPv4 days and seems it will stick around for a long time, and we need solutions sometimes around those topologies.

Are you conflating a router with SNAT? Routers as in L3 routing are not an "IPv4 only abstraction."

Yes I used it in place of NAT for most casual users at home, which is presumably what the user above originally meant.
