We even see this with FFXI, which does allow this, where RDMs are often healers in small party content because they can heal well enough for the content while also doing more damage than the main healer Jobs. If you can't heal enough in White Shift, then there's no reason to be in White Shift - bring a healer to heal and stay in Black Shift the whole time. On the other hand, if you CAN heal well enough in White Shift you don't need a healer, then why would any party bring a healer when they can White Shift RDM it and get more damage? Not to mention RDM as healers would be amazing in FFXIV since they would be able to chain Raise, freeing up that "utility Raise" Caster slot for BLM. This would also make SMN useless in 8 man groups that had a RDM healer.
All the other would do is the theorycrafters would say which is better for a given fight and everyone would slot it. We had this in FFXIV in SB and there was always a "BiS" for the Role Abilities for each fight. WoW tends to even have this where there's always a "best Talent choices" for any given fight, though there's often an "here's a second set that doesn't math as high but is easier/safer to pull off".
The reason WoW got rid of the in-depth talent trees years ago is because they said it was an "illusion of choice" as most of the time, there was a right and wrong way, and if you weren't doing it the right way, you were bad. Some spects had a handful of points you could move around, but they were pretty insignificant, like Wrath Holy Paladin (healer) getting to pick between "Do I want to make Wisdom better or do I want to make Kings better?", and if you had more than one Paladin in your raid team, it was irrelevant anyway since one brought one and the other brought the other and that ended the debate.
EDIT: You say that White Shift RDM wouldn't be able to replace a healer in even 4 man content (other than with a WAR tank), so what would be the point of White Shift? Why would anyone ever use it? "I'm going to do less damage so I can provide a utility that the party doesn't need and which doesn't actually let us trade out a healer for more damage"? It's kind of like how PLD can absolutely heal with Clemency in 4 mans today. But...no one ("good") does because it's a DPS loss and you have healers healing instead. If Clemency could REPLACE healers, then it would be more valuable even at a DPS loss (the solo AST healing Ultimate had their PLD using Clemency quite a bit, but it was a DPS gain since they were able to sub out the second healer slot with another DPSer), but it isn't.
Likewise, if White Shift COULD replace a healer, then it would be valuable, but if it doesn't, then no one would use it. And if it COULD, they everyone would be replacing healers and you'd open that whole can of worms. :ENDEDIT

Stuff like that works in more free-form MMOs like Everquest, but not in "polished" ones with well established theorycrafting communities like most modern MMOs.
NOTE: I say this as a person that LOVES that about old school MMOs. I would LOVE if that was viable in FFXIV. The problem is that FFXIV's combat system is too rigid and its theorycrafting community too entrenched (and too obsessed) for that to not be highly disruptive and destructive in FFXIV.
