They have to draw a line, simply because development resources are limited.
So they will give you a *range* of options, and in fact FFXIV's engine is quite scalable, but they will basically never give them all.
Sure, obviously there has to be development time allotted to create all the different options, but that's not a valid argument against adding options, especially in an MMO. These days people expect PC games, especially MMOs, to provide a wealth of customization and options to the player.
