It is a trade off. How much did they really gain by using ?. A year ago I helped a small company with some issues. One was that some people working with them had some problems using their app with older phones. After some investigation it turned out that I just had to replace "let " with "var " on a few lines of javascript code. I used an an Iphone 4S for the testing and the browser could not be updated. I you make something that could work on older devices and it is not too much trouble, you should make it work on those devices. I have a drawer full of old devices that I use for all kinds of things (besides testing) where it is not a big deal that the software cannot be updated. I do have an old chromebook. It runs Debian sid and has updated browsers.
