So I do not see him changing this.
Also in regards to FFXI's 'style lock' glamour system, it's actually locked to only allowing gear wearable by your current Job (if you change Jobs the style lock is deactivated and the glamour appearence deleted), but players found a way around that and exploited it - because SE ignored it players then thought "oh that's by design", except it isn't and it's just that SE didn't consider it that harmful and just let it slide.
Given FFXI is in it's Indian Summer, no wonder they're less flustered about things like that than they are here in FFXIV.
