To be honest, this is something I noticed while working on something else and it didn't seem right that the attribute wasn't preserved, but I didn't think too much about it. The one case I can think of is annotating when accepting an input tensor if you know it will be backed by aligned memory, but maybe that's not being used/theoretical? I am happy to just close the PR if alignment on tensors should not be allowed. Maybe the verifier should be updated then to ensure we never accept alignment when operating on tensors? Wdyt?
