I was more wondering whether it's "search engines sucks" or "google
sucks" - obviously g search is dominant...

Compute a similarity metric ;). No, I'm not serious.


I wonder if it's worth adding some more metadata to our pages for
google's benefit. Perhaps it'd be *slightly* less annoying to navigate
to the right version of the docs if we added breadcrumb annotations
https://developers.google.com/search/docs/data-types/breadcrumb#json-ld_1

I can imagine - but have nothing but intuition to back that up - that we
also make google's job harder by having very recent timestamp for each
version of the docs. Perhaps we ought to add datePublished /
dateModified annotations, and freeze datePublished to the release?

And probably also not update dateModified when the page didn't change,
but I think you were discussing that elsewhere.
