The specific case addressed here is about JSON values large enough so you no longer can evaluate, e.g., [?length(@) < length($.a)], in exact numbers. This is a bit of a luxury problem, as 2**53 bytes ⩰ 9 Petabytes. Backblaze reports they can store a Petabyte for some $35000, so this is not an entirely hypothetical case any more, and will get less so during the time the spec lasts.
