This is a bit of an Epic Epic, and currently contains, but potentially not limited to improvements on:

• Languages (goal: avoid having to use translation helpers)
  • If language is not provided take SiteAccess languages into account before falling back to main language, all over
  • Only load one language, treat language params as priority like now on search
  • Reflect this on ContentInfo name as well
• Add lazy loaded properties for simplifying use of Repository
  • E.g. like $location.content and $content.contentType and other examples pioneered in NetGen Site API
  • including lazy load existing properties that are known to be expensive to generate, like $contentType.contentTypeGroups
• Multi get support for all/most domain objects for optimized lookups 
  • Both on missing and on not readable items, these are not returned in results in order to avoid exception handling 
  • Should also take into account language api changes from above
• Native Location drafts (goal: get rid of preview issues)
  • (however needs to make sure queries using data from this draft works as expected, with workspaces children should be queryable for instance)
• Visibility (goal: move to permissions to get rid of boilerplate code)
• Site knowledge (goal: somehow natively take care about path prefixes and such)
  • Open question is how to avoid having to do with and without lookups for UrlAlias.
• Domain Types (Like Object Wrapper, allow more logic to be moved to type as opposed to templates/controllers/commands, examples: Asset, Site,..)
