Forgive me if someone else already thought of this and I missed it, but am I the only one who thinks it's the exact opposite? Formless seems a very deliberate title. Shallan is TERRIFIED of giving up her multitude of personalities, of facing her past and avoiding more mental gymnastics and blocked memories and splitting her mind. My first thought was the Formless wasn't a new alter at all, but the lack of an alter. The true, unbroken mind and personality of Shallan, as whole and as traumatized or capable as she truly is without all her coping mechanisms. It's something she needs, but refuses to acknowledge or consider, even though the Veil alter has pointed it out. To someone with such a carefully broken, shattered and contained mind, embracing her past and just being herself without the alters and memory blocks and such might well seem lacking in form, structure or rules. Shallan claims her current self, the Shallan we knew before the alters, is just as fake and weak as the others but I really don't believe that; even if she made an alter personality as a child, it wouldn't be dominant with no competition or change for a decade, and she wouldn't have needed her constant, often excessive, coping mechanisms before making Veil and Radiant. Unfortunately, her self worth and confidence in herself is absolutely nonexistent, so she sees no value in her true, unbroken self (either because of her abuse, trauma, or likely both). I am only on chapter 12 or so, but I really do hope Shallan can get better. Both because she deserves it, and because I'm not particularly fond of her bickering with herself all the time. I know Sanderson did a good amount of research, and certainly he'd know more than I do on the matter, but I just don't see how Shallan could possibly say the next ideal or ever improve her mental health and relationships with a bunch of alters bouncing around (and the constant threat of making more under stress, which she worries about).
