it's definitely true that most of our users are deploying configs and applications so there's not a lot of user management, but the user management is definitely robust.

We're using GNU user tools in many cases for correctness and efficiency of not reinventing the wheel so you might wait a little more for them.

We're open to tuning but it's really not been a problem.

It's still statistical noise in the end, and, yeah, like we said, we've got more important things to work on first. It would be nice if we had time for everything, but this just doesn't rate in the grand scheme of things right now, still.

Someday, perhaps! Meanwhile, try things out, I don't think this will matter in practice for most folks :)
