The phrase "members of the 10 Northern Tribes of Israel who went into oblivion or assimilation" as opposed to "the Ten Lost tribes"

I might be getting a bit pedantic, but when biblical scholars use the phrase "The 10 Lost Tribes" then isn't it a bit misleading? The reason being is that the biblical passage 2 Chronicles 11:16-17 does mention that some of the members of the 10 members of the Northern tribes of Israel do settle in the Southern Israelite Kingdom of Judah: > ( 2 Chronicles 11:16-17 ) > > "And those from all the tribes of Israel who set their hearts to seek > the Lord God of Israel came to Jerusalem to sacrifice to the Lord God > of their fathers. So they strengthened the kingdom of Judah, and made > Rehoboam the son of Solomon strong for three years, because they > walked in the way of David and Solomon for three years." Furthermore, Jeremiah 31 which was written long after the Northern Kingdom of Israel was taken into exile by the Assyrian kingdom does mention the Ephraim( representing all the 10 Northern Israelite tribes ) by emphasizing that God did Not forget Ephraim: > Jeremiah 31:20 > > New American Standard Bible 1995 > > 20 “Is Ephraim My dear son? Is he a delightful child? Indeed, as often > as I have spoken against him, I certainly still remember him; > Therefore My [a]heart yearns for him; I will surely have mercy on > him,” declares the Lord. Therefore, it might sound comical but isn't it more nuanced & better to use the phrase "members of the 10 Northern Tribes of Israel who went into oblivion or assimilation" as opposed to "the Ten Lost tribes" ?
