[Breaking Change] Local Network Access (LNA) in WebView2 - is this being indtroduced, or fixed

[pjc2007]

Hi just looking at the issue MicrosoftEdge/WebView2Announcements#126

Backstory
I have an Ionic / Angular application which I host inside a .net WPF application, and use Webview2 to render the UI. We have a lot of users, who run demos using a local server. I had a user who reported the application would just not connect to his localhost. The ajax call returned no useful information, but from the dev tools I would see it being blocked.

One suggestion was to change

AppWebView.Source = new Uri("http://app/index.html")

to use https

AppWebView.Source = new Uri("https://app/index.html")

This fixed localhost, but then the QA team could no longer connect to their http only test VMS, i.e. non localhost (mixed content error). The the app is reported as broken

So the Webview2 ajax is useless to me, I had to forward all calls to use the hosting applications .net httpClient

So, is the above issue about fixing this, so we can use either http / or https, whatever we choose to use on either localhost and or remote servers? Sure everyone should use https, but it is just not the case in the real world (with test servers behind firewalls etc). I really could not tell which way it is going, fixing this, or causing this? We should be able to decide which we allow?
