My first thought was: why?

But on second thought, I can see how it might be useful.

But then my third thought was: i wonder what kind of security exploits people are gonna cook up

This is the most insane shit I've seen in a long time

I have to give Microsoft credit because this looks great. I can feel that people in the finance, accounting and professional services sector will eat this up.

Although I am not fond of the Python code running in the cloud, with all the potential security problems Macros and VB scripts cause, that's probably a educated choice.
