Yeah I agree it would be nice to not be limited to Slack. I plan on offering it to Microsoft Teams, Discord and other popular chat services.
I have never seen ZenHub before. Thanks for sharing. I just checked it out and it looks like it's a browser extension. I've thought about doing something related to a browser extension but thought that would be more development for me and I'm not sure how cool companies are with an extension that could read your Github. I'll dig deeper on it.
Yeah I was going to offer email as an option as well.
1. I've heard the death-by-slack-notification complaint many times hehe. My way to combat this was to offer scheduled digests that could be daily/weekly or whatever frequency. It doesn't have to be slack it could be sent to email.

3. That's true. I think a lot depends on having the right amount of notifications...nothing more, nothing less. Unfortunately the native github/slack integration does very generic things that it's not that useful. That is why I am trying to be more specific.
