druntime supports registering of GC's not compiled with druntime.

But because some of the machinery isn't available to you, you would have 
to recreate it.

So in practice you cannot find a GC on the dub-registry to try it out. 
Even if one were to exist, you would have to do a new build of 
druntime/phobos special which isn't the easiest thing to do.

Regardless, its a barrier to anyone wanting to try writing a GC to 
experiment with (or port one).
