While DPS or healer could work in theory for RDM, DPS loses some of the "hybrid" feel, and healer would end up strange in melee. (While other games have had melee healers, FFXIV has a history of mechanics that only target healers, requiring them to separate from the rest of the group, so a melee healer would either mean that healer was undesirable for fights with those sorts of mechanics or they could no longer include such mechanics, which would limit raid design).
Edit: To expand and counterpoint myself a little, the only reason they might not go tank is more of an aesthetic one. While RDM has usually worn "light" melee armor, including chainmail, they usually haven't worn the really heavy stuff (like the Wolfram tank set or the Noct set, for example). Most tank gear in the game isn't all that heavy anymore and wouldn't be a huge thematic stretch for RDM, but if they ever move back to an art style with larger pieces of tank gear being common, that might steer them away from making RDM a tank class (unless they did something weird with their gearing, anyway).
