Yes, me.

As I explained a few times alrady to some people, it is simply not
possible to standardizing the CONTENT. All you could do is standardize
a common subset (which will be extremely small).

Except for the fact that all controllers process SCSI commands in _some_
way, there is not much commonality in architecture and capabilities.

Over the whole range of supported controllers, they are about as similar
as a wall brick is to the Empire State building.
