This is why https://developer.apple.com/documentation/safariservices/sfs... exists and why the blog post advocates for using it.
In many cases I'd like to stay within the app. Those in-app Safari Webviews allows that. And if it is a website I'd like to browse in my usual, more permanent browsing evironment I always have th eoption to do so.
This two step approach is more useful to me than always opening links in the browser.
