The important thing to understand about subprojects is that they have members, and parent projects do not. So the membership of parent projects is the union of all subproject membership.
That isn't really needed for this because essentially labs-project-requests will be used as a tag, not as a group.
So a standalone project is appropriate in this case.
Actually, upon further consideration, I think the most appropriate choice would be a milestone of labs - milestones get a column on the parent project's workboard and milestones to not have members.
