From my perspective, even if this OP_RETURN issue isnt as big of a deal (either way) that people are making it out to be... more implementations means more safety from big sweeping changes on the network and protocol level.
I'm pro Knots, not necessarily because of OP_RETURN, but because I think its good for everyone to know that they can't control bitcoin. There must be consensus. For the software, for the protocol, for network as a whole.
