Indeed. However, I believe it's appropriate (given the requirements for
effects on reliability) that a proposal should be able to require (or at
least "strongly suggest") particular accept/reject behaviour.

The local administrator can choose to eschew (or modify) a particular
system if it doesn't fit local requirements. Where a system/protocol makes
requirements which go to interoperability, a good implementation will
usually abide by them.
