When Power BI was released, I was working with customers to try and adopt DevOps for their database code. At that time, I thought the Microsoft developers had made an extremely poor decision with the PBIX format in that it wasn't well suited for version control. In 2011, when it was first released, we not only had decades of knowledge about version control and the power of DevOps, but we'd also been living with the extremely poor format of code in Integration Services packages (among other data tools), that were poorly suited for understanding in version control systems.

Power BI has grown, and with the Fabric announcements, there are integrations with git for your workspace. There is also a Power BI Developer mode that saves your project in a folder structure rather than one file, which is better. I'm not sure it's great, especially if it doesn't enforce text in a way that ensures a developer can easily see changes between settings and understand them. I can certainly diff the XML in two SSIS packages, but that doesn't mean that it's easy to understand what has changed.
