It's not secret, but it's not exactly easy; you can find one part of the medallion just by exploring (iirc its description says what it's for), but not sure if the second half is that straightforward.

And even then, while an item may say "use it here", if it's been dozens of hours since you got it you may just straight up forget about it.

That said, I think that the target audience for the DLC was always people who thoroughly played through the game.

Same with the other games' DLC; for Bloodborne's you need to be yoinked by an invisible enemy while in posession of an item; while it's very possible people were accidentally yoinked on their first playthrough, they will forever know that the item is a trap and will avoid getting yoinked.

(unless the item in question explicitly said "get yoinked to go to DLC", I forgot)

Oh, yeah, the Snowfield itself is secret enough, but getting to the palace afterwards is just a matter of exploration. The teleport is not that hidden.

FWIW, after you get one half of the medallion, get invaded by Gideon's lackey and then talk to Gideon, he will tell you to look for the Albinauric woman, so at least they give you this much.

All in all, I find the quests in the base game relatively straightforward, but anyone with any prior experience in their games will have an inkling that if they care about quests' results, you need to double-check with the wiki.

Well for DS1 DLC, you had to kill an enemy from one of the latest area you unlock, then go to the back of an early zone, without any indication that you had to do so.

That's true, but it is strange that you get there and get early-game upgrade materials, like Smithing Stone 2, etc. It seems like they wanted to emphasize that the Scadutree Fragments are the important things for scaling, and not your Base Game level, but you already have to be pretty high level and upgraded to beat Mohg.
