I can't disagree with you there - while I did spend some time in the Chrome debugger to see if I could find some clues, at the end of the day I'm stingy with my time when it comes to pull requests, largely based on the # of open issues on the repo. Maybe I'm jaded but after losing a few hours to pull requests that never went answered and reading multiple different takes on github etiquette, I tend to play that safely.
