Some things just cannot be pair programmed. They are simply impenetrable to average minds at the time.
Your argument sounds like one for a Handicapper General, to be honest. (If missing the reference Google it). You want to handicap everyone actually competent with a slower partner. And before you claim the usual: it is ok to write suboptimal but simple to understand code, consider that in some cases we actually DO care for performance and size of code..
1) A very small amount of code
2) Isolated from everything else
3) Conceptually easy to understand what it's accomplishing (even if the implementation itself is interesting and non-obvious)
Most people would kill for a colleague who wrote code like that.
No, instead what you most often get out of people like the OP is mentioning (because I too have worked with and been burned by them) is some weird pseudo-ORM they wrote from scratch because they don't like how Hibernate handles joins.
Naturally, there's no documentation or even comments because it should be obvious why paxos was poorly implemented in this weird pseudo-ORM framework. And of course, the entire codebase was rewritten overnight to use this new framework as well.
I do agree that sometimes managers want to fit "chefs" into a McDonald's like cooking process.
This is a well known major impediment for creative persons in any field. You can explain things after they are done, not while you are doing them.
This is why average developers create such a drag on productivity. They always want meetings, explanations -- in short, anything that slows down the work horse and make them look productive in the process.
The "10x" works 16 hours a day for 3 days and produces a chunk of code that works, does what it's supposed to, ahead of schedule. So far, so awesome.
But the rest of the team is working away on the rest of the project. Suddenly they're lumped with a huge chunk of code that they don't understand. They weren't involved in the design decisions, they didn't pair-program or brainstorm any of the code. It's pretty impenetrable. And the "10x" who wrote it is now unavailable after that "heroic" sprint so they can't even ask questions.
Teams work together. Heroic sprints of productivity followed by absence is not working together. It's leaving other people to clean up your mess while you claim the credit.
