This term of yours "mono by default" I find jarring. I know "default" has two meanings but you seem to be using it negatively. Maybe it's just me but it makes me feel like you're settling for mono because you have no other choice?
I know I'm probably projecting my own stuff onto your situation. I'm on a bit of a crusade to be a "positive mono" because I tired of people feeling sorry for me. That's obviously why it triggers me.
