2D: getContact not seemingly documented

I can find a lot about getContacts (plural, returns array) but can't find much about an interesting autocomplete that showed up in Rider: getContact

Is this new or otherwise not long for the world of Unity?

It's exactly what I want, because it only (should) return information about a specific contact, which I'm presuming will be indexed 0 if there's only one.

Have I got that right?
