One thing that would solidify RPIs for anyone is using AMD-based architecture chips rather than ARM.
Obviously there's a power issue (afaik)and several other issues, but ARM support is hard for many projects. I know you can build docker containers for all architectures via qemu/buildx, but for stuff like Longhorn by Rancher for example or even Envoy (I believe) dosn't support ARM for some weird reasons I haven't gone enough into.
