Thank you for kickstarting this discussion @sdalu, to provide some context, here is my comment from #1532:

I appreciate you were probably looking to make them first-class citizens like the others, and potentially make them methods like Faraday.copy or connection.proppatch, but I feel like that addition feels unnecessary in the core Faraday library.

If you'd like to see that happening, then my suggestion would be to instead build an extension gem (faraday-webdav?) that adds these verbs to the list of allowed verbs and also defines the missing methods ❤️ .

Happy to further discuss here how that extension would work and look like.
@sdalu is this something you'd be interested in working on?
