Some composite charts are quite annoying to be generated well (like bullet, waterfall etc), their Vega-Lite equivalent can be quite long if just starting from scratch.
The intention here is that Flint is a simpler abstraction to get basic setups right and any followup edits can be done on top of the first compiled outputs (thus not limiting expressiveness). It also makes it easier for user to manipulate (like swapping axes, click to change something, which can be very hard if LLM generates a complex chart spec upfront).
But for many basic stuff your intuition is completely right.
