The launches do add a number of clicks to complete ingesting translated content.
As a first step I usually explain why we added this, for review and approval of translated content. Especially useful in combination with the side-by-side view capabilities that were added in 6.3.
To help address the issue, in the upcoming release AEM 6.4 it will be possible to set translation projects to automatically promote translation launches and to then delete them. The launches will still be created, but they will be transparent to the end users. This is an option in the translation project settings.
Post-AEM 6.4, we are considering to take this another step further by making the creation of launches during translation updates optional. This is futures though, will require investigation, and therefore not yet plan-of-record.
