Tag a v1.0.0 version

Could we tag a version 1.0.0?

That would make it much easier for packages that depend on this one here to use semver compat bounds in Project.toml. The problem is that pre 1.0.0, every minor update is considered breaking, whereas starting with 1.0.0 one can use the full semver semantics, which make everything easier.

Also, it seems that this package is so widely used with the current API, that one might as well declare what we have as stable and done, right?

Start by checking Project.toml for the current package version and reviewing the repository's existing tagging or release conventions. Confirm that the current API is intended to be stable, then determine whether the v1.0.0 tag can be created; done means the package is tagged at v1.0.0 for semver-compatible dependents.
