> Why would I ask annoying questions when I can identify, reproduce, pinpoint the bug, locate it in code, and fix it?

Because if the bug is sufficiently simple that an outsider with zero context to fix, there's a non-zero chance that the maintainers know about it and have a reason why it hasn't been addressed yet

i.e. the bug fix may have backwards-compatibility implications for other users which you aren't aware of. Or the maintainers may be bandwidth-limited, and reviewing your PR is an additional drain on that bandwidth that takes away from fixing larger issues

If the maintainers are already bandwidth limited, how is first asking annoying questions not also a drain on that bandwidth?
