People choosing a non local keyboard usually require this level of adjustments for daily use of their computer. If you want to type french with a standard US keyboard for instance, it will require at least some small layering. Typing a CJK language will require some more tweaks, in particular the dual action on keys saves a lot. If you intend to type both accented and CJK with let's say the UK international layout, you'll need every help you can get. When using vim more heavily, having an escape key remap as the control key's single action is also a huge QOL. Once you're in it, it opens the door for a lot of small improvements.
