I partly agree, the RPi Zero W is my ideal small physical computer with a full OS. Running it only from the overlay filesystem (to keep those terrible SD cards from becoming corrupted). Pi-Hole I run from a docker container on a fanless NUC-a-like. But for anything that needs GPIO, the Zero W is great (nice that this Radxz has a RP2040 built in to cover that).
