Oh yeah, I hand-write config parsers all the time. Don't we all? Also, anyone using ints in Python to signal boolean values is a terrible person.
I am routinely interrupted at work because I've got a lot of institutional knowledge of our codebase (and I'm the proxy product owner), and I wouldn't have it any other way. If people have a question that I can answer, then the sooner I answer it then the sooner they can solve their problem.
But I suppose this is aimed at people being interrupted by Joe from sales.
