Unfortunately I don't have now permission to publish the time-seq
graph about it but I've tried to improve the changelog messages so
that you can better understand under which conditions the problem
occurs.

It is indeed extremely unfortunate that you wish to justify a change
for which you cannot provide the supporting data at all.
