Any deadline will be declared either too short or too long. That's why the deadlines usually tend to be on the shorter side to put actual pressure on companies needing to implement them. However, the companies always have a way to say "look, we've tried our best, it's just we just need more time". No one is going to fine them for not meeting those deadlines if the companies are actually working on implementing the changes in good faith.
