Per feedback given in the original feedback thread before dropping supervised was announced: basically all aarch64 hardware that isn’t raspberry pi is dropped. e.g. OrangePi.
All hardware which requires additional drivers (kernel modules) is also dropped since modifying HAOS in this way makes it unsupported (the current stance). An example of an unsupported x86 eBay machine would be one where wifi requires drivers.
HAOS cannot be run in a lot of configurations and the purpose of dropping support is to avoid the support conversations in these scenarios.
I understand you’re sharing there’s alternatives for operating HAOS and I appreciate that. But generally, if supervised is your only means of operating HA besides a VM, then one would need to acquire alternate hardware.
