SheetJS: Doing support work for the open source libraries is: not particularly interesting, time consuming, and uncompensated.

If there's any regret, it's probably the amount of time spent doing support work for the open source libraries. It's not particularly interesting (usually pertaining to something in the README), time consuming (everyone seems to have their own secret project that they don't want to discuss, so you have to draw out the underlying issue slowly), and uncompensated.

Throwing random code over the wall is fairly harmless, until it sees any level of popularity, at which point you become the sole point of contact for a sea of people expecting bug fixes for free. That can be rewarding, but it can also be intensely draining.

I'm currently trying to offload one project because it's getting too much, and just finding a new maintainer who knows C and Python to a decent standard has turned out difficult. None of the regular project users have stepped up. Shrugs
