Would it be sensible to make this a configure feature: if C++20 is explicitly enabled, use it? It’s in the standard after all. But auto-detecting it is perhaps unnecessarily fragile.
No, we should just static_assert for [[no_unique_address]] being available on the platforms where we expect it. That is, anywhere but on certain MSVCs.
If we make it a configure feature, we open the door to BIC problems as we might accidentally turn it off in some builds.
