Generally, anyone writing a paper about something that could benefit from bugfixes would love to accept them, but doesn't have the time or resources to actually do so - unless there's another paper in it. If they have somehow managed to find enough personal time to have a hobby project, then they probably do accept bugfixes - and you should get them in before that person burns out.

It also doesn't happen enough to design for - I once presented a fairly open-source contributor friendly project at SciPy that I hoped would be compelling (it was about modeling the zombie epidemic), actively asked for help, had set up a couple open requests of varying levels of complexity.

I think there was one pull request total?

The juice just didn't end up being worth the squeeze.
