Should C3 refocus the export options for desktop/steamdeck? Webview2 no longer has plans for linux or mac support.
nw.js and electron support windows, mac fat binary, linux/steam, so seem like good candidates, as far as I know, only nw.js/electron windows really supports overlays
Other options, Tauri?
In terms of steamworks support which is somewhat related to export, greenworks has started updating again with later versions of nw.js, which is nice. Greenworks and Greengrinds addons work with this.
Another option is:
github.com/ceifa/steamworks.js
Which works well on electron (and can be compiled for nw.js with a few hacks). It has more features vs greenworks and is actively supported. Electron supports overlay on windows. Another benefit of this build is that it is agnostic in terms of recent nw.js releases, you don't need to update with every new release.
MS notice on cancelling Mac and Linux dev for webview2:
