Ligatures are nice but when you want to show the code to someone, or when you're reading a snippet for reference, you need to know exactly what keys to press to make that symbol. Assuming everyone knows the underlying glyphs for a combined ligature is not productive. I wouldn't want reference websites and documentation to use these fonts for example.
