Minor dev suggestion: don't turn Kotlin warnings into errors except in CI

[dae]

Making things like unused variables hard errors makes it more cumbersome to comment out a section of code while testing.

I see what you're saying, but in our experience twice now with the GSoC avalanche, getting errors prior to CI is a big win for us, we push hard for detection of all things that would fail CI to fail immediately on a dev workstation and only through the accumulation of a lot of marginal gains like that are we able to survive March/April/May as maintainers

Is there some more trivial local hack you can do to swap out the rules list?

[dae]

Gotcha, I'll do that then.

Implemented in ecdf4ad in #11644

That's a good tradeoff - I like that, local failures pre-CI has been a big help but an override for those that can handle a foot-gun works for me
