I think they're reading their audience and making the correct product choice.
Home Assistant users are the power users of the home automation world, but even among their user base I think the number of users who would use a full set of groups and permissions controls in their home is very small.
This is a feature that would take a lot of engineering effort and only make the product more complicated for most of their users. The part of their user base that did use it would probably never be happy because they wanted something even more specific.
Their basic permissions and control structure covers most of the common use cases. Going further would be 100X more work for something that would only be used by a very small minority of users.
