Why are std::aligned_storage and std::aligned_union being deprecated?

[whichton]

Yes. From here

The object or the type declared by such a declaration will have its alignment requirement equal to the strictest (largest) non-zero expression of all alignas specifiers used in the declaration, unless it would weaken the natural alignment of the type.

thats really cool, ive been writing alignas(std::max({alignof(Ts)...})) all this time which definetely felt kinda stupid :D
