it make sense to make the residual warning conditional on sd_is_zoned()?

I.e. is lbpme=1?

u just blacklist the mode select on the device in question?
Something like:
if (us->fflags & US_FL_ALWAYS_SYNC) {
sdev->skip_ms_page_3f = 1;
sdev->skip_ms_page_8 = 1;
sdev->wce_default_on = 1;
}

I must be missing something. How is always_sync different from just

We don't know whether a discovered device is "a simple drive".

We deal with broken devices by blacklisting them. I suggest you try to
find a way we can reliably identify your UAS devices. If there is a
common pattern, we can entertain adding a workaround.

RAID devices communicate the stripe width through the Block Limits VPD.
