@zkne Thanks very much for this PR! Can you have a look at the failing tests? Indeed, it would be great to have the improved population of the page content cache.

@fsbraun thanks for reminding me of this PR. I will update it in the following days.

@fsbraun Can you please check the PR now, I've updated the tests.

test_editing_plugin_changes_page_modification_time_in_sitemap wasn't written correctly as you can see with the new assert I've added.

@zkne This looks really good to me!

I also tested this w/ versioning which monkey patches both PageContent.objects as well as Page.page_content_set. I do not see a side effect there.
