The SD card idea is possible, depending on what the hubitat staff decide.
PoE is probably not coming. Why make hubitat physicslly much larger and $15-20 more expensive for a very niche feature? A PoE to microusb adapter is the way to go.
And in my relatively large system, my C7 has no problem keeping up, so im not sure we need a faster cpu than the c8 pro. Many people think it is unnecessary, but if you are having poor performance, try setting up an automation to reboot the hub nightly. It did wonders for my hub.
In fact, I automatically reboot both my linux servers, my phone, hubitat, my openwrt router, my NAS, ans my printer every night, and I reboot my laptop every few days. The only thing free from needing reboots is my iPad.
