We wanted Plasmic to be the source of truth for certain things (the css, the composition, etc), so that it is possible to re-generate code from Plasmic and continue iterating on your designs (design-to-code is never a one-time thing!). We've designed the generated code to be very instrumentable; you can pass in prop overrides for any part of the component, swap out parts of the component with other content, etc., so you can get the component to do what you need, without having to edit the component code itself.
