You seem to have missed the last line.

The issue isn't so much how old the characters are, but how heavily established. Most characters have one or two short stories about them, a fairly limited pool of lore, but comic book characters have DECADES of constant new lore, development, and ever-growing recognition.

Not everyone is going to tell at a glance a character is based on someone from a fairy tale, but you can bet your ass dropping Batman into Remnant is getting that character called out immediately.
