The sales pitch should be that it's faster (if indeed it's faster), or easier to configure,
or smaller to deploy... not that it's written in go.
So contains more useful information than saying "easy to deploy".
in fact, the type of project that sees something that works exceptionally well (like ES) and then decides to partially reimplement it (to the point of maintaining API compatibility) is a pretty big red flag that it is NOT going to be easier to use in the long run.
