The current behavior here is intentional -- in fact, LLVM will move towards returning poison for loads from uninitialized memory in the future (though precisely how this will happen is still uncertain, see https://discourse.llvm.org/t/rfc-making-bit-field-codegen-poison-compatible/63250 for some recent discussion on the topic).
