Re: Directory Upload

Thanks for the status update, Ali! And kudos for the transparency around
your plans for the prefixed APIs.

Re: the new directory upload proposal [1]

It looks like there's some recent discussion [2] by Moz folks about moving
forward with implementation. On the Chrome side, we're definitely eager to
hear about implementer experience and developer feedback on the proposed
API. We'd love to start the work to deprecate Chrome's prefixed APIs once
we've got a good path forward charted.

For those who are looking to check some boxes: you can cite this as
"positive signals" from Chrome, although we have no commitment to implement
at this time.
