I feel like I'm seeing an error, or I just don't understand what they mean w/ "find" and "Integrated port of the original DOS command" and not listed as conflicting.

There's a "%SystemRoot%\System32\find.exe" on every Windows NT-derived OS. That's absolutely a conflict.

Also, the "find" command from "findutils" is in no way functionally similar to the "original DOS command" (which is for finding text in files).

Aside: Eschew "find.exe" on Windows for "findstr.exe". The latter is vastly more efficient. I discovered that by happenstance once and have trained my hands to type "findstr" when I mean "find" on Windows.
