To be honest it never really bothered me once I realised that a lot of iPad apps let me rebind the caps lock key to work as escape. I'd just love for them to make that option available globally like it is on the Mac.
Not only that, but also native KeyUp and KeyDown events[1] without needing a JavaScript hacks! This means keychord-type shortcuts are now also possible in an app that wants to use it (e.g. an IDE, if someone is building one), or app-specific key remapping (e.g. Blink.sh, which currently uses JavaScript to detect and remap the key)
