Considering Oje UI 7 is still under development and if samsung developers do visit community discussions it might be a feature in one ui 7 as everyone is requesting and needing it, even though no leaks confirm anything of this sort, there's still time to implement it. It's highly required and important. Being a samsung customer samsung wallet is a deal breaker for me and many more for storing documents in an efficient way. However if I'm not able to protect it without 3rd party app locks with ads then it does kind of misses out on point. Having a system enabled app lock would not only help in keeping apps that are constantly being used ( e.g. instagram, office apps ) in main homescreen and simultaneously protecting it while giving out our devices to someone else. Secure Folder is a different universe within our galaxy which are not for public but app lock creates a universe where you can see the application but can't visit it without permission which would also be really important
As a long time user of samsung, there was one app lock provided by samsung 2 3 years back named S Secure, Samsung should be bringing improved version of that app.
