Dev fonts is usually synonymous with fixed width (mono) fonts, and for good reasons. Those reasons are discussed by iA Writer in interesting detail [1]. However they do so as a precursor to their own duospace font, "iA Writer Duo" [2].

It's a compromise, but one that works well (for me). Basically IBM Plex but with m, M, w, and W being 50% wider than all the other characters.

Sounds odd, but is very legible and usually fine depending upon the context of its use.

All of those "good" reasons seem to boil down to nostalgia. Monospace is a historical technical limitation, nothing else.

Proportional fonts are simply more legible, and programming with them is great.
