Here's an example of a new API they added recently (the first one I thought of):
https://msdn.microsoft.com/en-us/library/windows/desktop/mt5...It says things like this:
> Indicates that the data for the file should be obtained from a WIM file. On access, data is transparently extracted from the WIM file and provided to applications. If the file contents are modified, data is transparently decompressed and the file is restored to the same physical form it had if this API were not used.
This is "boilerplate" and "very little content" to you? What are you thinking of?
