Because probably this was pushed due to meet some OKRs ("made an impact").
It adds nothing over runas, other than being a known name to folks educated in UNIX.
Which is hardly of any benefit, given that Windows is not UNIX.
It seems like this adds much tighter integration between the caller and callee processes used named pipes and RPC communication, such as being able to share input/output streams within the same terminal session, which is a significant value add compared to runas.exe.
