There's still e.g. https://chrome.google.com/webstore/detail/backspace-to-go-ba... but IMO it's ridiculous to not just make this an option. Hide it in a flag. https://venturebeat.com/2016/08/14/restore-backspace-shortcu... they decided that 400k users was not enough to warrant a flag for.

But hey, cmd+q to quit immediately, with "warn before quit" off by default is a great idea. No need to look at that one or make it possible to change the key bind. Never mind that it's one key away from cmd+tab.

This is the kind of stuff you get when you make decisions based on A/B testing.
