It would be nice to have a Sigstore client listserve that can help automate communications that need to be delivered to Sigstore clients, including:

• Deprecation notices
• Breaking changes or updates in services
• Security issues
• etc.

It would be nice to also have tooling around creating these emails via a GitHub issue. E.g. if we post a public PR/issue on sigstore/community regarding Sigstore services. Then with applying a certain label or comment, we can issue an email to the list-serve with the content. Or maybe that's too complicated, but it allows for documentation of the issue outside of a listserve if public.
