That's still consolidation, and it also needs time.

Even in Rust crates like hashbrown or parkinglot have been basically subsumed in the standard library.

Agree, after I thought for more examples. Thanks, don't know why others downvote.

Besides consolidation point, I still think that "barrier to entry" point is still valid -- if it's more effort to even publish a library, its author is probably more committed already.
