in my opinion its totality depends on Samsung, and Samsung developer, core version is not actually an issue, if Samsung decides and develope for core ui then its practically possible, but almost no chance however You can send feedback to Samsung by using get help section
GetHelp>>SendFeedback>>ErrorReport/AskQuestion>choose appropriate section
before that we thought secure folder not supported core ui which was correct, but fortunately Samsung developer team develope for core ui, and m31s already got
so its possible but not possible if Samsung not wish to provide
