At this point, I think it's mostly being used to it as nightly was more convenient for a long time. I've currently switched to nightly to use the 2018 edition changes already, which will soon be unnecessary. Almost all libraries work fine on stable now. (the new async/wait support is an exception, but it's still very experimental right now and not used by many) Important note: You can always develop on nightly and get potential speedups etc, but not use any features and then deploy only with stable.
