Thanks for the amazingly detailed reaction, it was a very pleasant surprise! I added a link to this article from mine.
About the article: I am still not convinced about the benefits of the synchronous nature, but honestly I will need a few hours (or days) to fully digest your article. I need some time to think about these issues, especially stale values. After that I would love to have a discussion with you. I plan to open a new issue in MobX or NX or write a new article, whichever works best for you.
About Proxies: I check the Proxy related MobX issues every few days and I would gladly help with the gradual migration. I don’t have enough time and TypeScript knowledge to fully do it, but I can help if you need some snippets and tips. Proxies are pretty awesome.
