Move from a tested library where when a vulnerability is discovered everyone in the world is made aware to an untested one shot llm output that if a vulnerability is discovered will never come to light .

What's the reason to switch to something less stable short/long term? Because its older and newer code is always better?

That's like saying rpad is well tested. Axios isn't exactly rocket science, it is trivial to replace. So much so that even a SOTA llm does it reliably. I'd say good riddance.
