So, could we CC someone?

So, if we keep the current situation everyone who ones such a buggy hardware
have the following options (IMHO):
1. create a udev rule, that sets "write through" for this hardware
2. using non-journal filesystems only
3. do not use this hardware anymore

But I think all that options are not good ones.

The udev rule will work on my machines then, but a USB drive is designed to be
mobile. And a mobile storage will be used on other machines, too, without
change some system stuff on that (missing permissions, ...).

I could understand if someone states that the hardware is buggy and there is
nothing to do. But I think this does not fit to the Linux Kernel. The kernel is
filled with a lot workarounds for hardware / implementations that is not
correct.

Could someone contact a SCSI developer, perhaps that stuff could comment their
ideas (e.g. for "if SYNCHRONIZE CACHE command is not working, fallback to write
through" and "what should happen when a drive really does have a write cache
but doesn't recognize the SYNCHRONIZE CACHE command").
