As some have pointed out many of the requests they provide are quite helpful and it could be useful to have an interface to browse a selection of optimizations that have been offered up by bots. What about splitting them off into a separate interaction lane to eliminate the noise they create elsewhere? A "Bot pull requests" tab. Make it passive, so it does not trigger notifications, emails or other active communication, but is available and streamlined.
