As a group, programmers do seem quite attached to monospaced fonts. For my IDE I have actually gone (I think) even further than you: I use a proportional (serif even!) font for all my programming, not just prose writing. It took a bit of getting used to, but now I've come to much prefer it over monospaced fonts.

Inverse for me, I use mono in places people traditionally use proportional fonts - after literal decades of looking at monospaced text (right back to DOS) it's just as easy for me to grok.
