Are there any plans to get Announcements use weak references?

I saw that in the repository of Lukas, there is a WeakAnnouncer. However, here the subscriptions are still held in a regular Dictionary.

Actually, I am not sure what is the status of weak references. I tried the following, but it does not seem to work:

| x array |
x := GLMPane new.
array := WeakArray with: x.
x := nil.
Smalltalk garbageCollect.
array size 

==> 1
