I used to think that way, but now my router is a Ryzen 5700G running NixOS so there is no reason to not hang some wifi radios off of it. Additional APs are low power amd64 motherboards (which also run Kodi to drive "TVs"), because I got tired of the ARM dumpster fire. Although I just ordered a pile of RPis to make security cameras, so maybe I'm back looking for a little punishment.
