#services intend to implement v2.0.0 of the page summary endpoint as it provides an opportunity to create a good example of how to implement RESTBase migration handlers (v2.0.0 -> v1.1.2, for example). Per T165017#3271061, what they need from us in order to start work is for us to:
 Specify/discuss any other major upcoming changes that can be done as part of the content type bump.
[x] Document which `textextracts` request parameters to change for v2.0.0.
* See T165619#3272926.
