Firefox has a marketplace with participation rules and enforcement where organizations that break the rules can be banned for violating them. That already exists. They want something stricter. What they're asking for is the ability to have multiple marketplaces and validation measures, some of which have stricter rules than others. That these requests pop up in scenarios where marketplaces already exist suggest that singular universal marketplaces that attempt to be one-size-fits-all gatekeepers aren't scalable or sufficient to meet everyone's needs, and that a multi-marketplace setup would allow some of those marketplaces to offer stricter quality standards for the people who need them.
