Yeah. It's weird how Unix picked LF given its love of terminals. CRLF is the semantically correct line ending considering terminal semantics. It's present in the terminal subsystem to this day, people just don't notice because they have OPOST output post processing enabled which automatically converts LF into CRLF.

I'd argue (but have no historical context) that it's a distinction between storage format and presentation interface, and IMHO that makes a lot of sense. A terminal has other operations too, backspaces and deletes being the most basic. Which coincidentally are one hell of a mess across different terminal types between ^H / 0x08 and DEL / 0x7f as well…

(And these distinctions predate UNIX — if I were confronted with an inconsistent mess I'd go for simplicity too, and a 2-byte newline is definitely not simple just by merit of being 2 bytes. I personally wouldn't have cared whether it was CR or LF, but would have cared to make it a single byte.)
