Because Python and JS are extremely difficult to use and extremely hard to understand for most cases that a user with no training in programming would have. Most people who have been programming a while disregard what a huge barrier to entry syntax is. Python's bizarre white-space sensitive syntax is especially bad for this kind of embedding. Another huge barrier to entry is the need for explicit iteration - the much more beginner-friendly option is to express operations in terms of their effects on the "selected" element in a list, or on the whole list, relying on the programming environment to actually handle the iteration. Overall, I think the approach taken here, of offering a beginner-friendly programming language AND environment, which exposes the resulting code as a data structure and not an opaque script, has some of the best chances of taking a PoC built by a domain expert and actually turning it into production software. Even better, it greatly expands what a user can do without ever reaching for a programmer to do it for them.
