Suppose Infra gave PMC members a way to commit with svn:author=svn-role, would that solve the problem? > >> Related question: Why don't we run the cron job more frequently? :) FWIW, when backport.pl was written, I scheduled it to 04Z because that was a time when most developers were inactive, so it was unlikely to cause conflicts for people by merging a bunch of stuff halfway through their workday.

If you mean <https://mail-archives.apache.org/mod_mbox/subversion-dev/201610.mbox/%3CCABw-3Yf6-B2JOMj58ZQDCLLOSpgdXZOWXEDGi0-TEYsr2VFCsw%40mail.gmail.com%3E>, it was fixed in backport.py at the time.
