I feel you've misunderstood his point. The stuff you (or anyone) perhaps doesn't like is stuff that someone else LOVES. I absolutely love writing docs and tests and fixing bugs, and would be willing to get paid less to work on public code that allowed me to spend what I consider the right amount of time tending to those things :)

It's upstreaming the concern, and just getting to work on the things he loves at a pay cut for the inconvenience of matchmaking
