I don't think "prompt engineering" was ever a clearly-defined practice. The way I see it, it's just some over-eager noobs both prompting and prompt-injecting until they get results close to what they want, and then subsequently pretending like they're engaging in some new branch of mathematical reasoning. Hence why I called the moniker "pretentious".

Personally, I've never liked the title of "software engineer" or even "data engineer" (my own title). However, those are more rooted in engineering-like practices than any of this "prompt engineering" nonsense.
