In my opinion, never a typical Qlik Sense functionality, like any other software product, will be enough to satisfy the requirements of absolutely all users - too many different tasks. Developers in any case will develop Qlik Sense, based on their own views.
Almost any missing functionality can be compensated by creating extensions Qlik Sense. To do this, Qlik Sense has all the necessary tools. But for the development of extensions, unfortunately, an entirely separate layer of knowledge is additionally needed.
