I think that's the most interesting part of this particular board - the built in RP2040 and 40 pin header for Pi hats. With the Pi 5 splitting off GPIO to an external chip anyways there really isn't much advantage to having a "real" Pi for GPIO/hats vs this - some stuff around firmware/software image integration for really complicated hats mostly.
I've moved on to N100s for most of the low-cost stuff but RPi HATs and the GPIO stuff give it pretty good future value for awhile, I think.
