This is not the mobile version, however. This is the same full desktop version as any other option covered by OfficeRTool, and accepts standard licenses, with the license determining the edition and version.
I'm not sure the API is useful in all cases. In particular: limitations on available deployment channels; lack of CHPE (arm x86) and arm64x (arm x64) references. I made a list of x64 files for myself and that's enough for me. If new files are added, it will need to be checked separately.

Hard to say. Different versions are mentioned internally. When downloading, the version of the main distribution is indicated. These files are not described publicly and are used during the update process. I have not tested the deployment time depending on the presence (absence) of these files when using the C2R deployment component installed on the system (not ODT). So I could not say whether these files are useful. According to the approximate view, the size of additional delta files can be about the size of the distribution itself, which means there is no obvious need to use these files. The cumulative period may depend on the update channel, when only the necessary files are updated, and not all products. I do not have tools for analyzing C2RxUnityDB (*.db), only hardcore "reading" of files =)
+1 for arm support. Instruction set currently supported by this tool are x86 and x64. Windows Arm based laptops are available now - and there's an official Office release for arm based laptops.
Will check it today tomorrow this week .. I need to check parameters for arm. most of my binaries don't support on arm based computer It wasn't plan to work on such machine
