FWIW, I've occasionally seen unreproducable recovery issues that could have been caused by this for many years now. This is effectively correcting a zero-day bug in the log behaviour. Here's the commit that introduced this behaviour: http://oss.sgi.com/cgi-bin/gitweb.cgi?p=archive/xfs-import.git;a=commitdiff;h=99b58644923246c710c6dc9f7b47bcae66ed3c63 Dated 4th May, 1994. It's definitely a contender for the oldest bug we've ever found in the XFS code base...
