Context-aware initialization allows to instantiate add-ons multiple times, most importantly in multiple Workers' contexts. Workers made first appearance in v10.5. Context-aware initialization was option earlier than that, even before supported minimum v6.x, yet condition is chosen more conservatively as NODE_MODULE_VERSION >= 64, a.k.a. v10.0.
