Any time they give a reason that there’s some technical thing they can’t accomplish, just remember mahjong. The devs programmed a fucking mahjong client into FFXIV (and it’s quite a good one too, on top of being free trial accessible, apparently some people get the free trial primarily for mahjong). If they have the technology and budget to do something as irrelevant and orthogonal as that, they can put in anything (as long as the devs are interested in making it). So basically it’s all bs, plus there are mods and plugins that do every QoL and visual upgrade imaginable already implemented as a third party tool.
