My only matter of contention with Steadfast is that it becomes a polar opposite of Parry: excellent in parties but is poor in solo (maybe with healer chocobo). But if we're thinking endgame, that's a stat I'd love to have as a tank.
Steadfast's power should be whatever the meta determines to weigh roughly equally to the damage opportunities lost with reduced Crit/Det/Speed. 1000 Det or Crit on a tank is certainly not going to make nearly such a noticeable difference; Steadfast would then be unlikely to either unless already pushing within 1-3% of death.

As for soloing, the only loss compared to traditional parry is in-class synergy with parry procs and that there isn't a forked path of possibilities (outside of being crit). Their average mitigation would be identical, and due to (percentile) boosted healing taken (including from one's own effects, such as Souleater, Clemency, or Bloodbath), would not necessarily perform any worse while soloing. What I mean by this fork is that whereas a tank could choose to forgo a minor self-healing ability (in favor of damage, etc) to avoid overcapping health after a parry, or a SCH could DPS for an extra GCD after using Adlo when the tank parries a 20k hit, Steadfast itself gives nothing to really work around (it will simply be basically 2% less damage taken, 2% more healing received at, say, 1000 Steadfast - numbers tbr). Inversely though, over a larger window, that measly 2% could skip a Physic. The main thing is where the parries would have hit--against a trash AA, little is saved, against a tankbuster, savings are tremendous.

That said, this is all over-debate; since even at 1000+ Parry I haven't heard of anyone's increasing their actual parry rate by more than 5%, compared against a much larger base parry and skills that guarantee the parry or increase rate by a flat chance amount (30% DD) as to devalue the parry stat itself, it seems that the portion of one's parry chance actually caused by the Parry stat is rather tiny, and that's the only part that would be replaced here.
