No, changing rdbms is a totally different challenge. They provide predictible reproducible output which are very sensitive and brittle to the slightest minor change in the input, while with LLM you expect the exact opposite. Changing the LLM backend in some IDE is as complicated as selecting an option in a dropbox for those who integrate such a feature. They are other scenarios where it might be a bit more complicated to transition of course, but that's it.
