MathJax transform in `\style` is broken

Ah ok, good to know. Is there currently a supported way to change the MathJax config via a plugin? I read some old threads (e.g., here, and here), but I couldn’t find anything more recent. It would be nice to be able to modify the safe extension options to add transform as a supported style. Is there any more recent movement on this feature, or still something on the TODO?
