Tile 1 x 1, new variant?

[Jaco van der Molen]

I just stumbled across this picture on the German Dr. Brick Forum. This is a tile that came with the new Bookshop building. Anybody else noticed this slight re-design of the Tile?

I have not seen this kind of brick physical.

And before we go into making it in LDraw, let's remind us all not to over-beautify the parts, as we discussed with the 1x1 round tile.
We could make it as a new variant though?
