IFWiki seems like a better place to try that, if only because it already has the infrastructure for free-form collaboration on or near per-game pages.
But it sounds like you’ll still have the problem of the fragmentation of bug info between possibly-no-longer-curated bug lists, projects like The Infocom Files, and this new repository of knowledge.
I’m not up on the state of documentation of Infocom bugs, but on a quick look (all of this is stuff you’ve linked to or in threads you’ve linked to):
- Grame Cree’s list appeared to have last been updated in 2003.
- Nathan Simpson’s addendum shows as last updated in November 2024, so it might still be possible to get new entries on there.
- The Infocom Files records bugs in GitHub issues. (Some of which get fed back to Nathan’s list, per the thread you linked.) On a quick look, lots of activity in 2021, dunno if it’s ongoing. (And the aims of that project don’t necessarily align precisely with documenting bugs in released versions of games – e.g.)
