It's nice to hear of someone who is a big fan of monorepo build systems generally, rather than committed to one build system for all use cases. Obviously, Pants team is very enthusiastic about Pants, but we also believe the most important thing is a good match between each codebase's needs and its build system's features. For Python use cases, we are confident Pants stands out. But we recognize that all three systems have varying strengths, and want every organization to have the best tools for their own needs. So we don't mind saying when someone may be better served by something else. Enabling developer productivity is ultimately what drives us. That said, what needs do you have, and is there any info in particular that would help you take a closer look at Pants' fit with those needs? Feel free to ask questions, raise ideas, open issues, etc. We always appreciate feedback, and try to be responsive to queries. Cheers!
