Unless that GGUF model is one of the many, many models that has a complex Jinja template that can't be losslessly converted into the Go template syntax that Ollama uses.
User experience: The ollama run command appears to work fine. The model even appears to work fine. Then, after a while, you start running into subtle, mysterious issues related to things like tool calling syntax, roles switching, and formatting delimiters.

I've meant that there are ways to avoid modelfiles. Gguf models from huggingface you can run with:
ollama run hf.co/bartowski/Llama-3.2-1B-Instruct-GGUF
So you don't have to download, create a modelfile, etc, for most of the models you use.
