[OpenLayers-Users] Delaying Layer Initialization

[GregM]

I would add that tiles for invisible layers are downloaded from server not
only on map/layer initialization, but also while layer goes beyond its
minScale. 
Value of minScale is making layer not downloaded while initialization but
after zooming to scale < minScale.

Is this already filled as bug in tickets ? Because I cannot find it. 

Is there any workaround for this for OE 2.4 ?
