We talked about ligatures in-depth in BT-001 bulletin: https://berkeleygraphics.com/public-affairs/bulletins/BT-001...

In short, we think 1 keypress = 1 symbol printed on the screen. That explicitness brings peace. But, we also think that ligatures are optional and many people like them (read about all the pros and cons in the link above).

That makes everyone happy.
