wins be default, in that it will always be the root of ‘SAFE’. The strapline could be something else and still that phrase would be acknowledged.
If ‘Secure Access For Everyone’ is the principal sentiment that is considered will have biggest impact, then I doubt there will be much disagreement for its being the one true strapline.
Still back to the OP… the thought is that any or all of the strapline could be used. If there is formal advertising then some consistency is useful but this is a decentralised network… let the message be communicated in whatever ways are most effective. Different thoughts and motivations appeal to different people.
