Hello Anand; At ROLL, we are discussing how the PCE could compute routes and use RPL signaling to install them (https://tools.ietf.org/html/draft-thubert-roll-dao-projection). This is independent of whether there is a TSCH network or not. If there is none, we do not benefit from the cell reservation and the associated deterministic properties, but we can still optimize the path based on constraints from a centralized perspective, and we still need 6loRH for packets.
Actually, the 6TiSCH architecture suggests (unless we change that in the future) that even for tracks, if the packet inside the track is an IP packet, then there is an RPI HbH option indicates the flow.
