Yeah, just a clarification here : I haven't wanted to bikeshed about the
trait name during our PTG session but I'm also not sure we have a consensus
FWIW, I'll ask about it on the spec but here, given I was saying "we agreed
on adding a 'XXX' trait", I used an adjective instead of a name.
TBC, we have both adjectives and names for our standard traits  so I'm
fine with both of the traits.
