 Replying to [comment:12 scantor]:

 > Indeed. That conversation has been non-terminating with no material
 change to the state of things for over 10 years now, save for one new
 contributor that has since departed. I'm simply putting folks on notice,
 that I'm moving on as of this coming year and if you honestly think
 somebody else will take over, then you can revert this decision.

 @scantor Do you have any advice for a replacement for xerxesc3?
