> This makes the interface very similar to TLO::SimplifyDemandedBits, do you know why that function is set to assume a single use?

The function has exactly one user in lib/Target/AMDGPU/AMDGPUISelLowering.cpp, and the behavior is necessary there.  (I haven't really carefully considered the consequences of it.)
