Why weren't the early Christians thinking of an assumption of Mary?

I've written some posts over the years about various historical problems with the claim that Mary was bodily assumed to heaven. See here, here, and here. While reading Stephen Carlson's book on Papias, I was reminded of a passage in Irenaeus that ought to be highlighted in this context. While discussing individuals who have been "translated" or "assumed" to heaven, Irenaeus cites the examples of Enoch, Elijah, and Paul. As I document in the articles linked above, we see the same pattern with other patristic sources for hundreds of years. They keep citing Enoch, Elijah, and Paul as individuals who were assumed to heaven, but never use Mary as an example. Irenaeus isn't just citing Enoch, Elijah, and Paul because they didn't die, as the surrounding context demonstrates. For example, he refers to "the translation of the just" and "the assumption of those who are spiritual" in general, regardless of whether those individuals had died. So, the disagreement among Catholics about whether Mary died prior to her assumption doesn't seem relevant here. And it's noteworthy that Irenaeus refers to how "the elders who were disciples of the apostles" passed down information on the subject Irenaeus is discussing (Against Heresies, 5:5:1). So, those disciples of the apostles Irenaeus refers to can be added to the list of sources who made relevant comments.
