It creates hassle for those involved, so you shouldn't make such a promise without asking them first. Also, if you did this, the people on the list should actually make a commitment not to leak the contents of the mail by talking about it amongst themselves in unencrypted mails, which we're not well set up to handle since none of our lists are set up for encryption.
This is partly why I want to split it up by role. Otherwise every person who has ever volunteered to help sort or parse or respond for any job has to .. what, get a copy of each key that we make?
Agree that just providing a key and not following through with keeping the content private is misleading. We haven't got a strategy for doing that yet, and our (my) intention is to share the set of candidates with the rest of the community. Is this problematic?
