Perhaps not. In this presentation, we will discuss what other aspects of a Project need to be assessed for long-term adoption. This includes factors like the availability of binaries and quality documentation, governance structure, community size and activity, along with several other important criteria. ## Speaker ### [Peter Zaitsev](https://www.wearedevelopers.com/@peter-zaitsev) Founder at Percona, FerretDB, Coroot ## Related talks at this congress - [Kettle and Pot or Peas in a Pod?
