Description

Many long-requested features for OAS can now be better handled by using the Overlay and/or Arazzo specifications.

I think Arazzo mostly overlaps with the Link Object, but I might be wrong there. Some guidance as to when to use which would probably be good to add.

Overlays solve many requests for global or default values, and if it is reasonably straightforward to do that, we should include info in the OAS pointing to the Overlay spec for that use case. Other use cases include various reference-and-modify constructs (hmm.. do we want to consider pushing this instead of the adjacent-fields-in-Reference-Object approach?)

Putting this in the next patch release, although there may be additional things to do in minor releases here.

Start by comparing the OAS Link Object with the Arazzo and Overlay specifications, focusing on the use cases described in the issue. Done means adding clear OAS guidance on when to use each specification, including global or default values and reference-and-modify constructs.
