I do not see different properties in the bindings, so what do you mean
that it evaluates something else?

Anyway, whatever driver does is rarely good argument for change in
bindings, because we focus here on the hardware, not on one, chosen OS

Depends. What driver does, might not matter in some cases. What matters
is if these properties are applicable to this hardware.
