+1 from me too.
This looks like a light weight addition with benefit for anyone wanting
to use Metacello, and no harm otherwise.
I have not tried unloading Metacello-Base, but it has no dependencies so
it should not be a problem. There is an #unloadMetacello method in the base
package that presumably performs as advertised.
