I live in Thailand; I'm extremely skeptical that it's going to happen. The most likely explanation is that a few powerful generals feel like this must happen and proudly announce their plans, and technical teams responsible for actually doing it feel too intimidated to explain to the generals why it's impossible, so they just agree to it hoping that the dictatorship will be out of power before the implementation could happen.

As someone from /r/Thailand put it, "I'm hoping incompetence and indifference would save the day once again, as it has many times in the past." They can't withdraw it now without losing face, but they can let it just wither and become forgotten over a few years.
