Vehicle Wrecks Cannot be Destroyed Anymore? (especially Tanks?)

As the title says - since Updates 1.2.2.0 it seems like the wrecks of tanks and IFVs (maybe even jeeps and air vehicles - didnt noticed this as of yet) take significantly longer to destroy/despawn.

Before the patch one could shoot a tank wreckage a few times so it would destroyed for good. 

Now it is not possible to make the wreck disappear - or it takes 12+ shots of an IFV... after two reloads i stopped trying.

Is this a bug or intentional? At least i dont see anything mentioned in the latest patch notes.

If this is/was intentional - why? Is it to create additional cover? This might be a valid point - but if one sacrifices ammo from the semi limited ammo pool of a vehicle, it should be possible to get rid of the wreckage. 

Or maybe let us push the wrecks aside more easily - or maybe add a "bulldozer thingy"/obstacle remover that we can choose as an upgrade for IFV and tank.

Anyone else?
