Hey, I am maintaining another fork of ai-deadlines, and hacked a little Python script that uses LLMs through the OpenAI API to "crawl" conference websites and keep the metadata in the YAML files up-to-date semi-automatically.

I do double-check its output before committing, but it works pretty reliably, despite the calls-for-papers varying widely across venues and time.
Just wanted to flag this, maybe it's of use for you, too!
