I commend your analysis but the issue isn't the mathematics but the application, a large proportion of people which play FF14 do not have as stable ping to double weave consistently let alone deal with Expanded arrows. Although it may appear that increasing your skill speed/spell speed increases your dps to a greater extent, will clipping your gcds do an inverse effect which is why balance is much more favoured. As there is no risk.
Keep in mind that giving healers spell speed is dangerous as mana economy is fairly flimsy and in prog content where res is required can this also be unfavourable.

But i could agree skill speed meta is comming into play with classes like DRG outputing significant dps gains with these builds
