I'm far from Google's biggest fan but I wouldn't depend on any platform remaining over a 5 year period and would instead avoid lock in. For example Heroku in convenient for Rails but it should only be a few days to a couple of weeks to migrate to raw AWS any other hosting solution if required. This may mean limiting the use of the additional features and services integrated with Heroku.
Providing portability was possible (and I haven't looked into this service so it may not be simple) if I was a VC startup my bigger worry would be that Google would have too much information about my operations, scale and growth that I would prefer they didn't have until I chose to give it to them.
Shame on you if you walk into something with half/no plan. Price should never be your single (or top) motivator for service selection; ESPECIALLY with something as crucial as a business dependency like IaaS.
