Useful WWDC Videos Missing from Previous Years (For example: "Customized Loading in WKWebView from WWDC 2017")

It appears a lot of useful WWDC session videos from previous years have been scrubbed from the developer.apple.com? I cannot find the WWDC session "Customized Loading in WKWebView" from 2017 in the Developer app nor on the developer website.

There are lots of other videos that would be useful to watch, even from years ago. Am I just not looking in the right place?
