Intent to Implement and Ship: Rich PWA installation dialogs - desktop

Explainer

https://github.com/w3c/manifest-app-info/blob/main/explainer.md

Specification

https://www.w3.org/TR/manifest-app-info

This feature has been shipped on Mobile - see previous status entry and I2S. 

Enabling this on the desktop uses the same "description" and "screenshots" fields.

We additionally implemented parsing for the screenshots' "platform" member, but that was included in the original spec and design.

Summary

Gives developers the ability to add more data (descriptions and screenshots) to their PWA install dialog and gives users more insight into the apps they are about to install. This implements PWA richer install UI on desktop. See previous chromstatus entry for mobile - https://chromestatus.com/feature/6422599217184768

WebView application risks

Does this intent deprecate or change behavior of existing APIs, such that it has potentially high risk for Android WebView-based applications?

Debuggability

Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, Chrome OS, Android, and Android WebView)?

Yes

Is this feature fully tested by web-platform-tests?

No, there is an open issue for this: https://github.com/w3c/manifest-app-info/issues/26

Anticipated spec changes

Open questions about a feature may be a source of future web compat or interop issues. Please list open issues (e.g. links to known github issues in the project for the feature specification) whose resolution may introduce web compat/interop risk (e.g., changing to naming or structure of the API in a non-backward-compatible way).

I see from the mobile I2S that https://github.com/mozilla/standards-positions/issues/492 was filed. Might be worth pinging that thread and pointing to this I2S, in case someone has input.

WebKit: No signal

Could we file for a signal at https://github.com/WebKit/standards-positions/issues?

Thanks for pointing this out! It would be nice to try to reach consensus on this issue before shipping, then maybe needing to immediately deprecate/rename the platform member.

One more question: is this correct link? It seems to be a TODO currently.

[Phillis Tang]

Hi Mike!

Yeah, I created the issue to ask if the spec editor can fill out the explainer more https://github.com/w3c/manifest-app-info/issues/57.

For the webkit and gecko signals - commented in the mozilla standard thread. webkit position is tracked in https://bugs.webkit.org/show_bug.cgi?id=222356.

I just got a +1 from Aaron on the platform rename issue and will work on submitting pull requests. 

[Daniel Bratell]

Positive feedback in bugzilla issues do not count as official support which is why we want you to file an official feedback request for WebKit as you've already done for Mozilla.

LGTM3 - thanks Phyllis for tackling the rename issue and chasing down the explainer improvements.
