Connect IQ 7.0.0.beta1 - App exporting is not supported!!!

Just installed Connect IQ 7.0.0.beta1.

Have performed a lot of code changes to replace Lang.Symbol for ResourceId.

Trying to export project and got error App exporting is not supported!!!

Is it how  7.0.0.beta1 designed to behave? What is the point to make it available via SDK manager without any warning project export will not work?
