I'll put it this way, I have a project I'm considering where both a Milk V Duo and a pie zero would probably do fine. But if I follow the raspberry pi example, there's dozens upon dozens of examples for me to look at. If I use the Milk V Duo I'm going to have to figure out that stuff by myself.
The libraries for a pi hat might only exist for the pi for example. I guess I could write my own library though.
Yeah, there's a difference in available public resources between a chip nobody knew anything about just 6 months ago and is just getting upstreamed to Linux in the current release cycle, and BCM2835 from Rpi Zero which has been around for 11 years.
Are you serious? :) At least compare with something like Allwinner H3/A10/... which had similar lifetime.
At the end of the day I know a raspberry pi chip will be supported 6 months from now. I don't know about a new RISC V chip that literally just came out.
