Let's be honest, if we did a release with only stabilization, it might get us more users. Not more customers. And it is customers who pay for the development.
Everyone asks us to focus "on the basics" and then claim their pet feature requests are, of course, basics. ACL's and user mgmt in your case, perfectly fine features, but features nonetheless.
In the end, our development is guided by the community and customers. If you're not either, we might not do what you want... That's the reality of any open source project.
And you're right, for a large installation, you should obviously get an onsite engineer, or, much better, a contract with us which is both cheaper and better. That's what most larger installations do, and that is how we earn the money to make Nextcloud better.
WRT the E2E, that sadly took a whole lot longer to get working than we had expected. Of course, if you think it is important or need it, time and money can speed it up, we have only so much of those.
