I'm aware of that, but:

 1. I don't want to have to remember an obscure version #.  It's much 
easier IMHO to have a symbolic
    name representing the point in time when the old allocator disappears.

 2. I don't want the change when IRA was installed, I want the last 
version of the tree before
     the old allocator goes away.
