RFC 2606 ("Reserved Top Level DNS Names") not RFC 2616 ("Hypertext Transfer Protocol -- HTTP/1.1")? I would have gone with the latter.
Related: I just noticed Cloudflare's DNS service (1.1.1.1) follows the suggestion in RFC 2606 and resolves *.localhost to 127.0.0.1. That can be handy for local web development etc. There are some other wildcard domains that resolve to 127.0.01 but I usually can't remember them.
