I think it's true for any early-stage library/framework. The tradeoff is then you will have to keep maintaining it, add support to other LLMs if you change LLMs, etc. Then in the end OSS will be far ahead because by that time it will have smoothened its rough edges.

Or OSS will be going in a different direction then what you need, so if you are using it you'll either be stuck on an old version or you have to keep fighting around it. ML libraries in particular have this annoying habit of not being very backwards compatible over more than 2-3 years.
