Following from this discussion, I have a question.
Sometimes when a WP/CP plugin/theme gets uninstalled it leaves something behind in code and/or database.
This may lead to sites expressing PHP notices, warnings and fatal errors and/or conflicts in some cases.
Can CP do something about that by encouraging developers to allow for complete plugin deletion? I do not know if this makes sense as a question, but I think since we are at the early stages of developing our own directories, this is one of the things we can improve from WP
