Reminder:
we intended to close the wide review this week. Please let us know if you have any comments by next Monday 30 Aug.

Much appreciated!

Hi @siusin, apologies for the late reply. We understand this is widely implemented by now, and we have confidence in the WHATWG that all of the features have been adequately vetted so we are going to close this.

Furthermore, after discussing this in a breakout today (present: @cynthia @rhiaro and me) we do not think it's productive to do such large reviews, at such a late stage. They demand a lot of resources, but it's too late for the effort to make a meaningful difference. Please instead ask for reviews of individual features earlier, before they are so widely implemented.
