It doesn't really scale. There's a de-facto limit of 2,000 characters [0] in a URL. HTTP/1.1 is not opinionated about URL length, but practical implementations are.

If your ids are UUIDs, each has a length of 36. If your URL consisted of nothing but UUIDs, you could safely delete 55.5(repeating) of them.
