We've found that different users want different levels of wrapping -- some (like you) are experts on the low-level tools, and choose to use our low-level compute, storage, and analysis services directly -- I'm biased, but I believe Google Cloud's low-level services have features, like preemptible VMs and nearline storage, that are a great fit for working with genomic data. Others want gateways into bioinformatics-friendly environments like R Studio and iPython; others want wrapped packaged services; others want point-and-click UIs ,etc.
