Hi,
We are not considering this change. By design, this feature does not support "reviewing" empty segments - i.e. translating from scratch is not supported in the bilingual export. A CAT tool should be used to translate any segments from scratch to ensure best productivity. So, as a consequence, it is important to make sure target segments are all available in the exported file. (Again, it's meant for review, not from scratch translation).
Thanks
Daniel
