Not directly. If somebody actively avoided paired work, I'd probably ask them about it during a regularly scheduled 1-on-1. And if somebody was doing a spectacular job mentoring/pairing/etc I'd definitely mention it.
That seems pretty reasonable. I'd hate to work at a place that "didn't enforce" something, but had it turn into a 15 pieces of flair type situation.
From my perspective, it’s a great way to mentor and facilitate knowledge transfer. It’s also great for working through coding roadblocks. It’s a useful tool, nothing more. Theres no mandate to use it at the office, it’s up to individual developers to use it appropriately and managers to facilitate it.
