In the previous post on the Fly.io blog (https://fly.io/blog/litestream-revamped/), a really cool thing was mentioned!

> In Litestream, we’re solving the problem a different way. Modern object stores like S3 and Tigris solve this problem for us: they now offer conditional write support. With conditional writes, we can implement a time-based lease. We get essentially the same constraint Consul gave us, but without having to think about it or set up a dependency.

Reading this blog post though, I couldn't see any reference to this. Is this supported in Litestream v0.5.0, or will it be for a future release?
