Whether using an attribute to input values of this type is supported, and the node group's input for this socket accepts a field rather than just single values.

static bool node_needs_own_transform_relation ( const bNode &  node )

Note

We can only check properties here that cause the dependency graph to update relations when they are changed, otherwise there may be a missing relation after editing. So this could check more properties like whether the node is muted, but we would have to accept the cost of updating relations when those properties are changed.
