ENB is an after effect and not a standard thing in the source engine, the same goes with the over the top lens flares.
We are always looking at ways to improve how the engine works for us but stuff like ENB isnt on our list as its not something we feel goes well with the Half-Life design.
By all means when the mod is released, the workshop is a perfect place for additional things like ENB & additional flare effects to exist so you should look towards thats for your effect needs.
