In the FOSS4G community the first question is often: "Is there a QGis-Plugin", and I've been asked this question already >1ce. So there seems to seems to be a user base and it would be a lot more convenient for them to just download it from the repository instead of the current installation process (apart from the increased visibility).
I therefore suggest releasing it to https://plugins.qgis.org/
