That's probably because they didn't want to favor any existing
implementation over others.
I don't see this as a problem with the standard not wanting to favor one
implementation over another, it is a problem because no current
implementation supports the new keyword.
That might have been the point: use a made up keyword that doesn't
exist on any implementation so as not to suggest that one should
be preferred over the others. (Just guessing.)
But I'm guessing wrong, of course. Again, I missed an important
detail in your post: that alignas is a new C++ keyword (I didn't
know that). Sorry, I need to pay closer attention.
Given alignas, aligned_storage seems completely superfluous. I
wonder why it's even still there...
