I found settlers and ships carried over to be not that big issue. Your settlers are waiting till they sail to the distant lands anyway, so it's not that big deal - usually you could just buy them.
I respectfully disagree!
In my current game I'm playing with long ages, and I had nearly 30 turns left without any useful/meaningful buildings to construct. So I decided to create a task force for the Exploration age, and I ended up with 8 ships, 19 scouts, and 17 settlers

Also, with a couple of future techs under my belt, I should get Cartography in only a few turns.
Both the east and west coast of my continent are littered with setups like this, ready to search for the distant lands:
Definitely a massive advantage, I'd say!
