Good points. Poke any abstraction enough and you will find holes in it. However, the question I was originally responding to was asking if same-level-of-abstraction-ness was fundamental to the definition of a transpiler. I would still argue that it is, in the common understanding of the terms. It may be the case that those terms are not particularly useful. Certainly from a technical standpoint, I would agree that it's not useful to try to force a distinction between transpilers and other compilers. If the goal is conveying the basic purpose of a project, maybe the term is of some use.
