I might try it (without spoiling course). So far I haven't really been able to get why certain maps are supposed to be hard. Sailing isn't hard, bosses further out isn't hard, except if you need go go through mistlands or plains to get to the Elder or something.

Of course having all the traders spawns at the edge of the map would suck moderately.

It usually is down to the novelty of say, need to use raft to reach a boss or even to get copper and tin in the first place, or perhaps traverse through more awkward terrain so early in the game there might be tiny bit more challenge and just slower start before the ball gets rolling. Or boss being surrounded by another biome or say, the closest Elder altar being ~30m away from bordering plains. Or that it takes bit longer to actually get your usual merchandise from Haldor.

Here's few seeds if someone wants 0.01% more challenging start than usual.
VanDamme
oskuhuutis
atolls
911SCRS (bosses used to be more spread out pre-mistlands generation but the starting island has remained the same)
