I'm afraid you're confused again, and may be unintentionally grossly
misrepresenting things.

Chrome has not eliminated the EV UI, nor has, to the best of my knowledge,
any other browser. While we heard that Apple updated their UI in June of
2018, Google simply moved how it treats EV information into a more cohesive
UI surface that's better aligned with user security. It sounds like Mozilla
Firefox has also adopted similar changes. However, all three browsers still
support EV, and still display UI, so statements like "eliminated the EV UI"
are simply factually wrong.

Perhaps it's not how you intended to come across, but it does sound as if
you're explicitly not interested in developing standards that can be used
by a wide variety of consumers. I would think that, regardless of any
disagreements about UI surface, we might agree on the need for consistent
results among all CAs, and that all certificates - whether DV, OV, or EV -
have identical levels of assurance, regardless of the CA that issued it.
After all, that's the core activity of the Forum.

Of course, if there's no interest from CAs in developing fair, neutral, and
consistent standards, I suppose it would be inevitable that the 'standards'
that are developed, but lead to wildly inconsistent results, would be
ignored or rejected by industry. After all, if the product isn't valuable
to those who would potentially use it, it doesn't seem a worthwhile product.
