Comment:

 [attachment:"39494.4.diff"] is a first pass at adding object schema
 support for both the `$taxonomy` and `"{$taxonomy}_exclude"` parameters
 via the new `oneOf` keyword.

 There was some discussion above about the naming of the object property
 for term IDs. The patch goes with `terms` for parity with the
 `WP_Tax_Query` parameter and for a potentially easier addition of a
 sibling `field` property later for querying by `slug` or `name`. But I'm
 open to switching it to `ids` or similar if the plan would be to use
 separate `oneOf` schema for slug or name queries.

 Given this uncertainty about how slug or name queries might be supported
 later, the object schema declares `'additionalProperties' => false` to
 "reserve" the space for future core properties.
