What can we expect from Apple / Safari in terms of Manifest v3? When/if will it be supported? When is the end of life for manifest v2?

I'm trying to put a view (html page) from a web extension into an iframe on a website. The html file is listed correctly in web\_accessible\_resources, however when I'm trying to load it, I get the following error:
Failed to load resource: The operation couldn’t be completed. (Cocoa error -1008.)

Since Safari 15, the extensions local and sync storage seems to be merged into one. This means operations in local storage apply to sync storage and the reverse.
This caused the users of of my extensions with more than half a million of downloads to loose all their user settings.
To keep compatibility across browsers, the sync and local storage should be separated.
When trying to Submit an update for review, I get the following message:

However, there is not any box where I can fill in copyright info for my app. What to do now?

Currently extensions are not allowed to load on iOS when the background persistent key is set to true.
To allow a single code base between iOS and macOS, it's very welcome to allow the persistent key to be set to true and accept it in iOS. As currently Apple doesn't want to support persistent background pages on iOS, Safari in iOS can simply ignore the persistent key and run the background page as if persistent is set to false.

When using chrome.windows.getAll to get a list of all windows. On iOS, you get two windows, 1 normal and 1 private.
Say the current tab is a non private window. And you then try to open a window in private in the extension. It opens kinda a ghost private window which hosts inside the non-private window.
Correct behaviour is that it simply opens that tab in the only private window possible.

Try to send a message from an iframe running a contentscript to the extension page containing the iFrame.
See feedback assistant report:
https://feedbackassistant.apple.com/feedback/9637664
The report includes a sample extension. If it works (like in Chrome), the text of the extension page should change to "success".

Contentscripts are not executed for frames within extension popups even with all_frames set to true.

To provide users the ability for a keyboard shortcut to open extensions, you can define this in manifest:
"commands": {
"_execute_browser_action": {
"description": "Open extension popup"
}
},
This doesn't set a keyboard shortcut yet allows the user to assign one.
However, in iOS safari, when two extensions offer this functionality, the browser warns about it. See screenshot:

The extension popups don't seem to support the dark mode media query.
The only way the query gets detected is when a color-scheme is added:
<meta name="color-scheme"content="light dark">
When including something like http: or https: in the connect-src and img-src directives of the contentsecuritypolicy of webextensions, they are simply ignored.
Other matches like https://*.example.com/ work as expected.

When the sandbox directive is included in the contentsecuritypolicy, even when it includes allow-scripts, it breaks all functionality from the extensions. It seems allow-scripts is simply ignored.

Currently trying to port a web extension over to safari which heavily relies on the include\_globs property of content\_scripts.
Is this something Safari plans to support?

Opening it in XCode immediately crashes XCode itself. Running XCode Version 12.0 beta 5 on mac catalina 10.15.6.
