I replied here https://github.com/llvm/llvm-project/pull/213468#discussion_r3804607662 about limitations of alignment values and  I agree with Dmitry that cases "Alignment == 0" and "Alignment is greater than zero" are different and we should check that runtime don't bring any handling on top of liboffload here.
