Should we run CI with Julia Nightly Version on PRs? #300
Description
moved from #299 (comment)
We run CI on Julia Nightly version, but only as a cron job (https://github.com/JuliaDiff/ChainRulesCore.jl/blob/decfca42702ff11a6c4b97c3563498e19415407a/.github/workflows/JuliaNightly.yml)
I don't know what benefit there is to the cron job, as i'm not sure who looks at it (and we don't want notifications, since Julia Nightly is broken somewhat regularly). So i think if we want to catch Julia Nightly failures, we might be better off having CI run on Julia Nightly on each pull request (and as usual just not considering failures on Julia Nightly to be blocking issues)
