Agreed. I think it might make sense to add a bit of text to all the drafts in this space. Would something like the following be useful to include in this and other similar drafts? "This specification is one experiment in improving access to public keys for end-to-end email security. There are a range of ways in which this can reasonably be done, for OpenPGP or S/MIME, for example using the DNS, or SMTP, or HTTP. Proposals for each of these have been made with various levels of support in terms of implementation and deployment. For each such experiment, specifications such as this will enable experiments to be carried out that may succeed or that may uncover technical or other impediments to large- or small-scale deployments. The IETF encourages those implementing and deploying such experiments to publicly document their experiences so that future specifications in this space can benefit."
I'm fine with adding this text to the Introduction. Paul
