The person is speaking about idiomatic rust code and seems to assume a large code base needs to always be updated to be in the most idiomatic stile. Most creates working on nightly only where tryfrom and async ones before that became stable. Now it's still common to find embedding and "crazy" creates (like there one which uses asm to hack in green threads) which work only on nightly. Most maintained creates work on stable by now, but it's not un-common to have some nightly only features. Honestly I haven't run into a created I wanted to use which requires nightly in a long time. The only crate which did cause me headaches in the recent year was ring (rustls,webpki) but that had gotten better.
