IMHO, the goal of Pharo should be to provide a minimal Smalltalk system where people Pharo can load what they need. Instead Pharo keeps on growing. I would prefer a system where I can decide myself what libraries and tools I want to use I am sure that the current Announcement implementation can be fixed, but does it really make sense that the core team bothers about something that could be external?
How can we remove systemNotifier? How can we remove the update/change mechanism? I think that this kind of feedback is not really nice to hear from you may be you should pay attention not to hurt people that I supposed were close to you and perhaps friends. But may be not after all. Let me repeat it again our goal is really to make a minimal core but not more minimal than useless. For me having a Announcement framework that does not work for RPackage, Moose, Glamour, ... is not good. Stef
