false.
Strictly speaking, you are correct, in that if one interprets SHOULD/MAY as
'not bother', one does not need to check, unless the presence of the remote
end doing the feature results in your barfing. However, if one interprets
SHOULD/MAY as 'bother', then one most likely needs to check on the
capabilities of the far end or handle the varying data elements or protocol
states that will or will not happen.
SHOULD/MAY is used for many other cases than whether to implement a protocol
feature that changes how the protocol works as viewed by its peer.
