Tf2 Sv_pure 1 Mods Euro Truck Simulator

Is it possible for somebody to add the new Valve re-skinned item models to the server whitelist.txt?
From what I understand, sv_pure 2 will not let you load them but what I don't understand is what is the difference between sv_pure 1 and sv_pure 2.
I know sv_pure 2 prevents game, weapon and world models/skins/sounds that would allow walling and other illegitimate things. Does sv_pure 1 do the same thing?
If we're committed to keeping sv_pure 2, I totally understand and would request changing the whitelist.txt.
Thoughts?
