[xwiki-devs] [Proposal] Support retro-compatibility for page objects

Hello. In XWiki, we take care of retro-compatibility. Each class that is not internal is considered as API, and we have clirr to detect when an API breakage is done. However, we don't apply this strategy regarding the page objects of our functional tests. I noticed this when I've tried to use some pages objects defined on an application based on platform 6.4.1 on an other application based on platform 7.4. Due to incompatibility issues, I had to rewrite some page objects in my new application. It will be a major issue when we will move some current core extensions to contrib. So I propose considered Page Objects as API, and to add CLIRR checks on the build. WDYT?
