Because its false thinking.
It is rather like this: These mechaniques and skills are being removed to focus on another class fantasy or an other gameplay experience. But in order to make people happy who enjoyes how the class has been they add these abilities back as talents so you can pick fromthem if you really want to.
Same goes for MM Hunters. They remove SV as a ranged spec but if you really loved the gameplay style of SV you can spec talents in MM to convert the MM skillung to be playable like the old SV spec.
Too me it sounds like a win win situation.
You can, if you want, stay roughly on the same level and gameplay style as before but you also could explore new ones.
Of course it will not be 100% the same because of balancing and overall design decision like the removal of ccs across the board, but you will be able to skill backdraft it is not completely gone.
And as a SV Hunter you will be able to skill blackarrow and lock and load. It is not completely gone.
