The current text does not allow directly targeting a primitive value, for example a certain string in the tags array of an Operation Object, and thus does not allow a convenient/workable way to remove or replace a certain tag name without knowing all other tag names in the tags field.

Proposal

Allow target JSON Path expressions to select nodes of all JSON types.

For example allow

overlay: 1.0.0
info:
  title: Remove a string from the tags array of all operations
  version: 1.0.0
actions:
  - target: $.paths.*.*.tags[?@ == 'dummy']
    remove: true

and

overlay: 1.0.0
info:
  title: Replace a string in the tags array of all operations
  version: 1.0.0
actions:
  - target: $.paths.*.*.tags[?@ == 'Foo']
    update: Bar
