Are browsers not able to patch manifest v2 back into the browser?

It’s unbelievable that so much of the gsuite on mobile web doesn’t seem to have been even touched in nearly a decade. It’s insane to me that they’re just ignoring that part of their own website even as it’s easily accessible.

Or as I did and switch to fedora! (Debian’s also a really good option)

It’s also available on plasma.
