Closing and leaving this as a reference:
https://devblogs.microsoft.com/cppblog/optimizing-the-layout-of-empty-base-classes-in-vs2015-update-2-3/

One can use `__declspec(empty_bases)` to work around the issue right now and a
future major version of MSVC might change the ABI to do that by default
(although there hasn't been a new major version since then).

Still wondering whether it might be possible, to not just silently miscompile
when using the differently layouted as parameters to CUDA kernels.
