The team has discussed the issue of submitted extensions that are scripts and it was decided that standalone scripts should be made available in the forum. In most any distro, there is a section in the forum just for scripts and coding as opposed to the scripts or coding becoming a package. In fact, I had decided yesterday to move my uninstall scripts out of the repo and will make them available in the forum for several reasons. Mainly because uninstalling is not an official method of TC, as well as not all WM's are supported so they are incomplete. A script existing in the forum does not mean it is of lesser value, it is just simply where scripts are best kept.
Scripts in the forum are very maintainable by their owner without having to wait for an update to be processed. This would especially be good for a script that downloads things from third party sources. They can be improved upon by others in the community and improvements by others can be posted, and it will all be available in one place and at once.
It is community's contributions that help make TC what it is, and we value all of those contributions. Please understand the decision to keep contributed scripts in the forum and keep the repo for applications and library packages.
