Microsoft is rarely completely clear when communicating product or direction changes. The primary reason is that things tend to change between inception and completion. It’s difficult to stick a hard target on a date and feature set when digging into the details can most times alter direction.
The recent announcement that Microsoft will switch its web browser, Edge, to run on Chromium has left additional questions about how it will work.
Microsoft has provided some clarification:
Existing UWP apps (including PWAs in the Store) will continue to use EdgeHTML/Chakra without interruption. We don’t plan to shim under those with a different engine. We do expect to offer a new WebView that apps can choose to use based on the new rendering engine.
We expect to provide support for PWAs to be installed directly from the browser (much like with Chrome) in addition to the current Store approach. We’re not ready to go into all the details yet but PWAs behaving like native apps is still an important principle for us so we’ll be looking into the right system integrations to get that right.
It’s our intention to support existing Chrome extensions.
