As far as I can tell, the 'diediedie' naming is historical; for example drafts for RFC 8758 Deprecating RC4 in Secure Shell (SSH) were named draft-luis140219-curdle-rc4-die-die-die (https://tools.ietf.org/html/draft-ietf-curdle-rc4-die-die-di...) and similarly for RFC 7568 Deprecating Secure Sockets Layer Version 3.0 which had drafts named draft-ietf-tls-sslv3-diediedie (https://tools.ietf.org/html/draft-ietf-tls-sslv3-diediedie-0...).

The mailing list archives also say that someone raised a concern at a meeting, which is why the later drafts were named -deprecate. (https://www.mail-archive.com/[e-mail]/msg09563.html)

I wonder if the origin of diediedie is a geek reference to the Usenet newsgroup alt.wesley.crusher.die.die.die, which was created not long after the premier of Star Trek: The Next Generation in 1987.
