Electron bundles Chromium, not Blink directly. Believe this is true of WebView2 too but am not well-versed in Windows internals.
In fact I’m not aware of any major non-Chromium usages of Blink, except maybe in Qt (where it replaced WebKit a few years ago) but I’m not sure about that either.
Isn't that what happened anyway? The non-Chromium dists of Blink like Electron and WebView2 both employ the same multi-process approach as Chrome.exe (and my RAM availability is suffering for it...)
