The Church knows who the Lamanites are

I was reading D&C 28:9, which states “… no man knoweth where the city Zion shall be built, but … it shall be on the borders by the Lamanites.”* The 2001 Church History manual took a clear position: “This referred to the border that existed from 1825 to 1845, east of which were the states of the United States, and west of which were the Indian nations. Part of that border extended along the western edge of the state of Missouri.”

Since this is from the Church website, is is it fair to say that, in this context, the Church does actually take a position on who the Lamanites are, and we can confidently say that the Church teaches/taught and/or believed/believes that the indigenous peoples to the West of the Saints were (or were a contingent of) those same Lamanites described in the Book of Mormon? I thought recently that the Church had shied away from this completely, but perhaps not?

*(Interesting aside, the original revelation said “it shall be among the Lamanites,” but was changed when published in the Book of Commandments in 1830).
