Yeah but the difference with all the different FF entries is that they are one of a SERIES while the KH birthday would be the birth of another series.

Generally i've been mostly underwhelmed about any of their anniversary stuff. I'm mostly judging of their Social Media and community interactions.

Take Blizzard for example. I laughed my butt off at the Overwatch twitter about "You've heard of elf on the shelf," joke they made yesterday. The blizzard accounts constantly interact with fans and it creates more unity WITH fans. They're more forgiving and more excited about new stuff. I feel like the company is more concerned and wants my attention because of this interaction

SE doesn't really care about fans or how fans feel about anything.
