"Conform from Identity" not available in 5.7 Preview even for Windows

For 5.7, there is a feature on the roadmap that enables Metahuman Creator support on Linux and Mac (https://portal.productboard.com/epicgames/1-unreal-engine-public-roadmap/c/2229-metahuman-creator-to-support-linux-and-macos).

Also, in this feature, it says “Note the ‘Conform from Identity’ feature will not be available in this release.” I thought this was directed at the Linux and Mac versions. But having just created the Python stub on the Windows version in 5.7 Preview, the “ConformType” enum is still missing something like “FROM_IDENTITY”. There’s only “SOLVE” and “COPY”. The same applies for the C++ header file.

So can I assume that this note in the feature was of general nature, i.e. “Conform from Identity” will not be available in 5.7 at all? Or does it mean that this feature will be available on Windows once the full version of 5.7 has been released?

Thank you.
