If you see a synchronize cache succeed and you then see the drive
shutdown succeed then you know that a sync cache can be faked as ok
safely. Any other command in between or after and it doesn't get faked

This seems pretty easy to deal with at command issue.

Probably not, but it will take a year or so and throughout this time
period everyone with the wrong combination of shutdown and kernel (which
will be a lot of people who compile their own kernels) are going to have
problems caused by what is a very obscure piece of libata internal
behaviour they'll never even know about.
