Steam integration (skins,workshop,cards)

Hi
I want to know if Operation Black mesa will use functions of Steam.
-Skins and items
Like CS:GO or TF2 has . I am sure you know what am i talking about
-Workshop
OBM could use workshop for maps (and other stuff) . It would be nice to create map in something like obm sdk and publish it in workshop
-Cards
I am also sure that you know what i mean

It can all look somehow like on this quickly made picture http://www.jpeg.cz/images/2015/03/25/bsmAf.png
