Unix followed Multics. Multics chose right. ASCII/EMCA-6/ISO646 drafts discussed this at least as early as 1963¹: “For equipment which uses a single combination (called New Line) [...] NL will be coded at FE₂ [Field Effector 2 = 0x0A].”

For an OS that was being created specifically to process text, having the equivalent of CR being separate to LF to allow for overprinting would/should have been a requirement.
I'd say Multics/Unix was technically correct, except this was still the wrong decision for I/O ever since.
The Record Separator is the logical character code to use to indicate the end of a line of text and print position characters, assuming that a line of text is a "record".
