It isn't a bonus to exploration if no matter how well you explore, you don't get the bonus. Requiring more sites might have been a positive change, but requiring every single one makes the quest impossible, and therefore irrelevant, in most games.
In my first game I had both marvel quests (one 6, one 12 required) done by turn 185 (on a standard map), so I wouldn't say it was impossible. Granted different games will present different levels of difficulty completing them, but I'm okay with that.
Note turn 185 is in the neighborhood of the mid-game for me with my games usually ending between 230 and 300. For those that prefer to race, the marvels will have significantly less value.
I also noticed the hydrocoral quest gives the ability to work the tiles. That seems new.
