Very useful if people are struggling to create reliable repro steps that work for me - I can simply debug in situ on their machine. Also useful if a coworker is struggling to figure something out, and wants a second set of eyes on something that's driving them batty - I can simply do that without needing to ramp up on an unfamiliar toolset. Ever debugged a codegen issue that you couldn't repro, that turned out to be a compiler bug, that you didn't see because you (and the build servers) were on a different version? I have. There are ways to e.g. configure Visual Studio's updater to install the same version for the entire studio, which would've eliminated some of the "works on my machine" dance, but it's a headache. When a coworker shows me a cool non-default thing they've added a key binding for? I'll ask what key(s) they've bound it to if they didn't share it, so we share the same muscle memory.
