I've been reading people use "postmortem" to describe software retrospectives for like... 15+ years.

Mostly in the opensource, or marketing-blog spaces. The detailed investigation and fix report was a favorite genre of blogpost. And if someone's bragging about the design of an enhancement, or investigating a bug, then the overall product isn't dead. They're (usually) not talking shit to anyone. It's the bug that's dead. Or security indecent that's over. Or a schedule milestone that's "dead and burred".

It's a 1 chili pepper level of spicy to use a slang term that relates to death. I'd never read it as hoping someone fails. I think people let the corpotalk center of the brain overreact to anything that's not couched in euphemism.
