I don't understand how I hit the anti-Rust tripwire here:

Not an anti-Rust tripwire. Just that WUFFS is the appropriate technology.
I like 4th edition D&D but if you're trying to make a story about nuanced inter-personal conflict in which there's no actual violence it's just not the right roleplaying system and so I'm not going to agree with your choice to recommend 4eD&D as the system for the story "Love and Jealousy in the Elven Forest"
I've written a whole bunch of Rust, and hardly any WUFFS - but, I wasn't writing code for Wrangling Untrusted File Formats and that's very much what you're doing in a PDF parser.
I am a big fan of WUFFS but some recent developments by people assisted by AIs writing format parsers in other languages has made me question whether it will be maintained or forgotten.
