[DX12] Texture2DArray descriptor used in shader as Texture2D

Hello,

I wonder if what I am doing is dangerous/non-portable...

In my program, all my texture descriptors are texture array descriptors (most of the time they are arrays of only one slice).

In shaders, I do not always use Texture2DArray but simply use Texture2D assuming that the first slice is used.

I did not see any warning, glitch or problems but I know that usually means nothing and that kind of stuff needs to be verified.

So... Is it bad? Like crossing the streams?

Thanks!
