Tabbed Application Mode is really supported across all three?

I know Chrome / Edge kept having issues with it being behind experimental flag and even the flag breaking and going away between builds.

Never heard of Safari supporting tabbed mode for PWA's

This is probably the biggest issue for me with PWA's windows.open actually opening a new full OS window sucks rather than a built in native tab strip.
