I think it's new.
Actually, this opens up the question whether modelers can create multiple skins with masked tints instead of full materials (vmts are MUCH cheaper than vtfs) for map props.
It's probably possible...
I think it's new...
It came with Alien Swarm I think. A certain prop type in Alien Swarm SDK can have its colour changed. This is just an overall colour change, and only works well on specific models (they are very neutral in colour, like grey or even just white with an AO map).
This is just adding a mask to that effect I think.
