No. However, there are many things that aren't in the documentation, I'm
working on a patch to add a note.

As far as I know, it is an accurate account of what happened in the
other thread, and as such is not slander. I just wanted to provide a
rationale for me fixing this bug instead of you. If you disagree that
this is an accurate representation, I invite you to summarise the thread
that caused this miserable situation of a known bug not being fixed for
a very long time despite appropriate fixes being known in your own words
for the commit message.
