It was removed more as a matter of "nobody used it anyway and allowing for
this feature in target designs was painful".
There are some new proposals that put some of this functionaly back in.
There is a proposal for WRITE and READ commands that have a scatter/gather
list attached and optionally have an "atomic" property that prevents other
commands from being processed.
There have also been an ORWRITE command defined and a COMPARE AND WRITE
command defined that do multiple operations in a single command, with no
allowance to be interrupted by any other command. Most people like this
better than linked commands.
