Ok, that would be those i7s which reportedly do
not support reading/setting the scrub rate, see
27100db0e0d381d24b6f3cb1a4f439996e7c00c8, for example.

So this is as expected.

Maybe it would be more correct if the core would return "N/A" or
"unsupported" or something to that effect in such cases, to conform with
the readable flag of the sysfs file.
