Demon Slayer: Kimetsu no Yaiba

then there is Tanjiro's birthmark, which gets bigger when he does this Sun(? can't remember)-breathing of his.

Isn't that mark a tattoo that he got over his original scar?

So obviously, there are connections established already and the memory didn't give us any more to work on imho.

Not for us. But it's giving Tanjiro information he wouldn't otherwise have.

I mean, why not just put the info in the book he's reading?

I'm not saying there aren't other ways.
I'm saying it's not a copout. (in what way is the author required to use that scene, he didn't have to at all - if he trusted the viewers more, they would probably get it without it)

As you mentioned yourself, it doesn't take much to get the information across. So for sure the author thought about how he wanted to do this and he did it "this" way. But it's not like he did do it "this" way, because he had no other way or couldn't think of anything.

Keep in mind that Tanjiro was mindreading, dream/trancewalking around in scenes he didn't know and talking to ghost and stuff ever since episode 1 or 2 in the first season.

I don't know what it is, but it expands and burns into a different shape when he does his super-breathing style his father once did when he danced outside in the snow.
