Agreed. There's a myriad of other ways to achieve this. Furthermore, this
simplifies overriding as a processor will know beforehand that an attribute set
is never going to consume and can inline the code without worrying about
streamability issues.

My stance is now that they can be removed from the operands (perhaps with a
Note), or alternatively, as we do with some other non-relevant (i.e., always
grounded) operands, add a note that this or that is the operand usage and role,
but that it does not influence the analysis.
