Adobe Analytics has some very useful builtin Reports in Analysis Workspace (and used to have some analysis Templates too). There are some helpful starting points for novice or casual users in there, from Traffic Sources to technical reports. Today, Customer Journey Analytics has no such option, but should.
Why is this feature important to you -
To help novice users start with something instead of nothing.
How would you like the feature to work -
Beyond the ability to use company-provided Templates, a Reports-like experience could be achieved if companies use the Adobe-provided AEP XDM Schema fields. For example, using the Web SDK mixin/field group would bring the potential to offer ready-made Reports and Templates in Analysis Workspace. The same is true for other use cases, like industry-specific analysis. Even beyond those, many templates could be built from builtin functionality already, like retention reports.
