On a 4k monitor you can still only get about 80 characters of monospaced font per line, because of the "negative space" fetish UX designers have.

Something dead simple like posting a stack trace, and then having someone able to, you know, read it... It's just not something teams really does well.

I can understand how the tooling probably does a ton of stuff that corporate users want (integrating with calendars, tons of access controls for spaces for important people to talk, etc) but for a dev working primarily with a handful of other devs and qas, there is a feature set mismatch. I can't begin to tell you how badly I don't give a shit about 99% of its features.
