This looks great @tianon. Thanks!

[yosifkit]

:confused: I'm not certain we should add even more data here; this repo is very much a hack of things that either ought to be exposed in a database or registry API, or presented in a friendly user interface. Creating more data for an automated user in our unstructured markdown should not be the focus.

[tianon]

Yeah, good point -- I got so caught up in "yes, I can add this to our data!" and excitedly implementing it that I didn't think about the purpose of this repository and how diff_ids doesn't really fit that. :sweat_smile:
