/22 that bad for production networks?

We've traditionally used /23 subnets for our production networks and I see us needing a little more growth options moving into the coming years. I've split out many of our networks into additional /23 subnets, but am seriously contemplating bumping them to /22's as well. That would make things so much easier, but I'm a little hesitant as I've read you shouldn't go larger than a /23 or /22 in some circumstances.

If I use a /22 subnet in production, is it really the end of the world?
