Should x-mitre-data-components have the domain added when exporting a STIX bundle?

[ElJocko]

Data components are considered secondary objects when exporting a STIX bundle, that is, they only are included in the bundle if they are referenced by a primary object. Groups are added the same way, and the STIX export adds the appropriate value to the group object's x_mitre_domains array. Should data components have the domain added to their x_mitre_domains array in the same way?
