To be clear, I love BYU Studies. I have years' worth of issues on my shelves. I use it all the time. Most of the articles are exceptionally well written and edited. And it rarely ventures into the realm of Book of Mormon geography.
However, right on its splash page, https://byustudies.byu.edu/, there are links to Mesomania materials and maps.*
Look at this one, for example. It shows a map of Mexico as the "plausible" location of Cumorah:
BYU Studies doesn't have to take a position on Book of Mormon geography, but it does.
If it followed the Church's policy on neutrality, BYU Studies would offer readers an alternative to consider.
It could show maps of a proposed geography such as Moroni's America that shows Cumorah in New York and thereby corroborates and supports what Joseph and Oliver and all their contemporaries and successors taught.
It's true that there are hundreds of different maps and it would be impractical to show them all. But really, the maps boil down to two categories:
1. Cumorah in New York (Joseph and Oliver and their contemporaries and successors)
2. Cumorah anywhere but New York (various LDS scholars)
For whatever reason, BYU Studies has so far told its readers only about the non-New York Cumorah scenario. It features this on its main page as if there are no viable alternatives.
I remain hopeful that someday, BYU Studies will trust its readers enough to offer them an alternative view that puts Cumorah in New York and fully explains all the geographical verses in the text.
