Request standards positions from Mozilla and WebKit

[reillyeon]

Given that we are getting close to launching an Origin Trial in Chromium for parts of the WebNN API it's time to request more formal standards positions from other browser vendors. This doesn't need to be a complete review, given that there are aspects of the API that are still fuzzy, but this is a conversation that should be happening.

Added to TPAC agenda webmachinelearning/meetings#25 to discuss expectations. Related feedback from Chrome #453 has been helpful for the group. Since that feedback was submitted, both Apple and Mozilla joined the WG that will help form informed positions.

Given we're close to announcing an Origin Trial for WebNN in Chrome (and Edge?) I would appreciate the editors requesting these standards positions. @huningxin @fdwr

https://www.chromium.org/blink/launching-features/wide-review/#signal-process has the guidance we follow, which includes links for requesting a standards positions from Mozilla and WebKit

Note that mozilla/standards-positions#1215 was recently filed

Same text for WebKit, more or less WebKit/standards-positions#486

cc: @reillyeon in case this can be closed.

I was expecting the editors to do this, but thank you @iampi31415 for taking initiative here.

[iampi31415]

You are welcome 😄 , I hadn't seen this issue, I just did it because I want to know their position.

Note that I've closed my personal request for positions to Webkit and Mozilla because I didn't sense any interest from them. The links are above so I won't repeat them here.

If you need it and want to re-issue them, you can use mine, or write some better ones.

Just letting you know in case it causes any inconvenience.

Re-opening this because I would still like the editors of this specification to request positions from Mozilla and WebKit when they are ready.
