We want this feature to be used for both external projects and for projects hosted in Launchpad. Right now projects in Launchpad are expected to do automatic imports of both translations and templates to use the feature, where it should be possible for them to just import templates to do upstream sharing. Importing both templates and translations is not only a bit of a waste, but unless the maintainers are really active in fetching translations from Ubuntu -which is not generally the case-, it can lead to overwriting new translation data with old one. A common example is the case where translations are automatically imported, but out of sync with newer translations from Ubuntu: in that case upstream imports have got precedence and will overwrite newer Ubuntu translations.
