Without it, there would not have been a transition phase.

I call BS. Without a series of MAJOR blunders Unicode was destined to succeed. When the rest of the world has migrated to Unicode, I am more than certain that Turks would've migrated as well. Yes, they may have complained for several years and would've spent a minuscule amount of resources to adopt the conversion software, but that's it, a decade or two later everyone would've forgotten about it.

I believe that even addition of emojis was completely unnecessary despite the pressure from Japanese telecoms. Today's landscape of messengers only confirms that.
