More effort has definitely been focused on the 'select' aspect, since you often select more than you mutate - and even in the future state, for data warehousing cases updates can be relatively rare. I definitely don't see it targeting core OLTP CRUD work, where abstractions can sometimes cause more problems then they solve - but I hope for projects that involve bulk data creation, analysis, and management - analytics like - it can be a complete solution once the 'persist'/ 'export' queries are developed further.
