If you want to make a quick shift from writing command line apps to writing GUI apps then you are the target for this. If you need to be writing high value mobile or desktop apps then this is a less of a compelling option as you note. There are a lot of very high quality libraries like Pandas and SciPy that are not available in the React Native ecosystem. Tools like those provided by BeeWare let you add a GUI quickly. The folks interested in interacting with something running on these data science libraries tolerate imperfect user experiences more than the average consumer. If we looked at React Native we could level your argument at it as well. Why use RN when you could build real native apps? Surely, that's the most optimal experience over a third-party platform, no matter how good RN is in practice.
