Sorry, by looking more into it I realized webview is actually a different thing than what I was thinking about.

This would be so good. As someone who fully switched to Firefox on Android I hate that chrome webview is a thing.

Why does that bother you? There’s also a Firefox Webview you can use system-wide. I think only Google apps insists on opening Chrome’s webview.

Do you apply the same reasoning for software that use javascript, the JVM, the CLR or some other kind of VM?

These are server CPUs, not something you wanna put in your laptop or desktop.
