You're surprised?

austerity is ~three years old. Much fewer people had multimon setups back then.

The problem is the community's ratio of user classes:
there are many users, fewer themers, and much fewer (module) coders.
I leave out artists, since there's supposedly one in everyone; they naturally help establish a userbase: putting more people on the problem could help I guess.

We need cooperation amongst these classes of users to help out the situation, since we have only a fraction of users with multimon setups, so then there's just that much less who can ideally develop/test multimon modules/themes.

Here's one way to look at it:
- Coders need to know how to make modules multimon-capable.
- Themers need multimon-capable modules.
- Users need to help solve the problem however they can, when just reporting the problem isn't enough.
Anyone can learn to do more and fit in more than one user class to understand and help solve the problem.

It will always be true that not everyone has multimon, so anyone with multimon should help however they can, since they feel the most strongly about wanting this problem solved.
