Not sure that the security concern cited by Marketo support as the reason this doesn't work, is valid...This should absolutely be a core, supported feature.

Agreed! Since it works on landing pages, how difficult a fix is this?

Going back to Forms 1.0. is not a solution, since we are giving up on other 2.0 features. This should be a high priority.

I agree - this will be very useful for those of us trying to avoid iframe embeds of landing pages for simple forms.
Technically it is possible to make our own prefill code using the Marketo SOAP api... but it's a lot of work to implement.
