Programmer A has been working with me for a long time, has done a lot of B- to B+ code. I trust that what he does is going to be up to that level.
Programmer B has been working with me for a long time and consistently turns in C level code. It isnt great, it isnt horrid. Call him pedestrian. When I get something from him, I know what it is going to be. Adequate. Not everything has to be great, most things move forward on adequate because there are too many things to get for B and A level people to do them all.
Programmer C is someone I don't know it all. Maybe I've heard of them by reputation, maybe not. Doesn't much matter, there is no trust there, I don't know what I'm getting. If I'm responsible, I'm going to vet their code closely. Make sure they follow coding conventions, best practices, etc. This takes time on my part. And my time is limited because now I am BDFL or some similarly ridiculous title that means "He's a busy guy".
