Thanks for bringing saphyr to our attention!

it is recommending migration to saphyr.

Maybe I missed something in my read but I didn't quite read it that way. yaml-rust2 is still supported. The distinction mostly comes down to what your tolerance for breaking changes / churn is. The fact that the version is only 0.0.3 communicates a level of instability that I would hesitate to take on at this time. I also would worry for the quality perception people would have in seeing a 0.0.x dependency in their dependency tree.

For now, I lean towards sticking with yaml-rust2 and that we can re-evaluate that as saphyr matures.

My main concern is if yaml-rust2 will get dependencies updated in time. So far neither of them have a dependabot/renovatebot setup. If they plan to keep them both updated, then yeah it would make sense to pick the more stable one for now. I have tried to contribute a renovatebot setup, but I couldn't cook up a minimal one to propose. Maybe you guys have more experience and could make a PR for that?

The setup I use for all of my libraries is at https://github.com/epage/_rust/blob/main/.github/renovate.json5

I thought that one had a required setup of labels and such. But yeah, it could work. I'll make a few PRs for those
