True, but on the other hand bugs can go unfixed for years, with developers ignoring them or prioritizing them super ultra low. I know I've opened enough bug reports over the years that I can't go back and check on all of them, but I'm still hoping they'll get fixed some day.
If it's closed for "inactivity" while I'm actively waiting for a response from the developer, that's going to annoy me.
As opposed to having forgotten about it. As in, if the developer responded, Github would send me an email and I would jump back into the conversation. As in I can't do anything more until the developer responds, but once they do I'm ready to help.
There's a quick and easy way to tell if someone is actively waiting: respond to them.
