Decided to give the WSC version a go. Not sure if I'll play through the whole thing or not, but I've already made a pretty interesting discovery: Enemy rows are still functional in this version. Seems they broke during the GBA port, not this remake. The targeting works the same way as the GBA version, so sometimes the enemy it starts you on is actually in the back row (three Dive Eagle formation near Baron, for example).
Thinking about throwing together a little site dedicated to documenting this version. "The Forgotten IV" or something. It's closer to the SNES version in terms of presentation than I remembered.

Tellah missing doesn't progress the Bard battle, same as the first GBA version.

Confirmed that dark knight Cecil auto covers critical allies.
Gilbert/Edward doesn't seem to auto hide. (Nevermind, just saw him do it.)
Gradual petrify actually works in this version, and seems to go much faster than in the SNES version. In addition to the light gray squiggles characters get in the GBA version, the character's sprite gets progressively grayer as they petrify. This isn't like the SNES version where they turn to stone from bottom up, they start with a dark gray tint and it gets more pronounced at the next level of petrification. Only certain colors of the sprite change, seems like they were going for skin and hair on Rydia, but Cecil's armor changes.
When I healed Cecil of stone status, the shades of yellow on his boots never updated and stayed gray. Stone bug affects Edward too, probably everyone. (Maybe this is an emulation issue? No real way of telling, but seems almost too obvious to overlook.)
Double turns seem to be present. Wasn't sure at first, there's no ATB bar to make it apparent in this version and it's not uncommon for Cecil to get more turns than anyone else in the beginning, but I've had the command window pop up
immediately after attacking with Cecil and Edward, same as the bugged GBA versions.
There's an annoying feature in the field equip menu where the item menu stays open even after you've equipped something. Additionally, trying to equip more of the same arrows will just swap the quantities instead of adding them.
I forgot to mention it, but elemental rods are single target, like the GBA version. Already knew about that, so I completely neglected to post it.
Bows and arrows seem to work correctly from both rows.
It doesn't seem possible to make a character permanently long range.
Yang's Power command seems to "charge" a lot faster in this.
