Accessing the size of individual 3d text characters via Python?

Am I correct that there’s currently no way of accessing/changing the size of individual 3d text characters via Python? There’s the object.data.body_format[0].kerning for example, where you can access individual character’s kerning values, but nothing for the size of the character.

It would be hugely useful to be able to do that, and preferably to be able to set drivers for that property. It would enable a non-destructive, non-AnimationNodes way of making the very basic ramping scale text effects, which would be a game-changer for me at least…
