No problem, I will work around it, I originally did not want to do it because of potential destabilisation, this still holds.

Comment (by simonpj):

 7.10 is in RC2.  We can't keep modifying it otherwise we will never get it
 out.  I suppose that if you have strong reason to believe that you are not
 introducing new bugs, and having it in is going to transform your life for
 the better, then you can make the case.
