I feel it's a lot like the Java enterprise world of FactoryFactoryFactory-classes - a col league coined the term "horizontal abstraction" for this type of trend; you never build a pyramid/hierarchy that composes truly higher level/abstract reasoning - you just complect in various constructs - that all keep hold of most of the complexity from the level "below".

So you get to write 30-40 lines of yaml for each of your ten slightly different services...
