As Terramex pointed out this is tied to a particular, relevant event. It’s also pretty common for Apple to preannounce some smaller features that are too specialized to be featured in the WWDC announcements. This gives them some attention when they would be lost and buried in WWDC footnotes. It is also probably an indication that WWDC will be full of new features and only the most impactful will be part of the keynote.
