(Almost) All the routers that people have in their homes - the ones running OpenWRT - have between 64-256 MB RAM, and no swap. Raspberry Pis are not "embedded", they are cheap, low power consumer devices.
Actually, modern routers typically have 512MB RAM. And RPis absolutely are embedded, not only are they often used for one-off embedded installations due to the 2-day lead time from Amazon, but also the compute module is very popular in industrial control.
