Explore the Possibility of Vouch Services

While Vouch switches the burden to the sender, this is a burden of parsing pages and finding connections. A webmention endpoint wishing to send Vouches could rely on an external tool to assist in finding possible vouch URLs by suggesting connections between two domains. This would have to be verified by the endpoint, but something like https://indiemap.org/ is a possibility for this sort of thing.

Start by reviewing the Vouch specification and the proposed indiemap.org service to determine whether it can suggest connections between two domains. Define the endpoint behavior, verification requirements, and project files or tests that would be affected before implementation; the issue does not currently specify a concrete done state.
