It happened 2 decades ago when 802.11 (WiFi) was standardized.
If you think about it, the standards that did shrink, shrank because they were on devices that were shrinking themselves. These physical ports were still needed mostly because there were cheaper/easier to do the same function physically vs Wirelessly. Power & Video are more difficult to do reliably in a wireless form. We're closer now than ever before, but this is the reason why they shrank instead of disappearing the way the RJ45 jacks did.
We will likely never see this change on a Desktop/Server because there's plenty of room with some of the other form factors involved. USB/HDMI/RS323/VGA etc are the original sizes. They are just too ubiquitous to change any time soon. If anything for Ethernet, While the unit size of the RJ45 as remained similar in size, they have added new standards that just pack more bandwidth into the same space: SFPs.
