Besides up-sells in plugins (and / or blocks) and themes, I would love for everything to gain the transparency that has been missing for years, particularly in featured plugins. There is no reason why the featured plugins section has plugins that sell services, one of which is even installed by default with WordPress, when, at the same time, there is such deep resistance to (other) plugins and themes looking to up-sell premium versions.

Guidelines and exposure should be the same for everyone.
