Nice to see us appreciated as "knowledgable and resourceful". 😊. And even better to know that you dropped the 20% "penalty" on using ]po[.
As for your question. The reason I am contemplating using ]po[ instead of project manager is simple. You are going to maintain it as a product. So I can be fairly certain that I could have a reliable Open Source project management solution which will be maintained and where someone has an interest in keeping it maintained even if cognovís is going in a different direction.
