If YOU understood anything about games development, then you'd know that it would be a rather simple task to repair it. So before you go pointing fingers check your facts.
As someone who actually works in 'games development', this is something that I know for isn't completely beyond repair.
A simply mesh deformer would fix the issue, but at the cost of processing time and memory which is why (for the time being) it wouldn't even be remotely considered.
But it's not a far fetched idea considering the original low-poly models and high-resolution texture layers used in version 1.0>1.23 still exist. All the original data for these still exist and are easily reversible to a certain extent.
This is what the FFXIV Forums are for discussing and expressing what you would like to be added, changed or adjusted.
Deal with it.
