IIUC there's an unspecified (probably non-public/not open source) project. You'd like to do some experiments with it (because you have access to it) and therefore you want to add some extra code (not useful for most users) to the public VM (used by everyone) to support that expriment. Am I right?
sorry, but you're quite wrong about that. a) if anything I produce open source artifacts b) I do research c) I work on pharo
I am looking forward to improve our system and having a state of the art compression library at hand might be useful. besides that I prefer shipping a slightly overloaded VM to the community for the sake of wider functionality.
For instance we have the SSL plugin by default now, which is kind of something you'd expect from any 2012 programming language.
We plan on adding the sources / ast to the image, a perfect use-case for a nice compression library.
