Hey @Hrellir, welcome to the Forum!
Thanks for sharing and we have some good news! The team is currently working on a new layout feature similar to auto layout and this relates to what you’ve mentioned.
Although this project won’t introduce a new container type (frames), the plan is to add frame-like features to groups like styling, so you don’t need to add extra layers to create them.
Groups already have layout features with Smart Layout, plus this new project now in development!
It’d be great to add your take in this call for feedback post 
Welcome again!
