On the Wikimedia Diff blog, one page is really not well suited for using the detect links feature since it contains several links to special pages with specific parameters.
At the moment, "detectLinks" is enabled by default on all posts. When we release the Gutenburg custom format, it may or not be enabled by default. We have to think about how to best allow configuring the "detectLinks" feature now and then.
One option is having it on by default with opt-out now and off-by-default with opt-in when we release the gutenburg custom format.
