Yes. The result from a reverse DNS lookup is almost never the right mailname. * Small installations tend to use a smarthost. * Large installations tend to use more than one machine, and only one machine's name gets the MX record. So except for cases where someone doesn't actually care about the recorded author and just has a script making commits (such users already suffer from the ".(none)" heuristic), I don't think this would hurt anyone. > We can put a deprecation warning in the release notes, but people tend > to ignore those. Not so much a deprecation warning as an "Here is one of the more noticeable changes in this release" announcement. I'm pretty sure a deprecation warning would not help here. Either people are affected and we say "WARNING: You were doing something perfectly reasonable, but now we discourage it", or, more likely, people are not affected. Announcing a change too loudly to users not affected by it has a very bad side effect of training them not to pay much attention to release notes.
