I know AWS services put outsized fees on things that don't really have marginal costs (e.g. S3 read operations), because the fees are used to disincentivize non-idiomatic use-cases (e.g. treating S3 as a database by scanning objects-as-keys.)

Under this economic-incentive-system lens, I'm curious whether new AWS services might also be intentionally started out with high premiums, as a sort of economically-self-limited soft launch. Only the customers with the biggest need will be willing to pay to use the service at first, and their need means they're also willing to put up with you while you work out the initial kinks. As you gain more confidence in the service's stability at scale and matching to varied customer demands, you'd then lower the price-point of the service to match your actual evaluation of a market-viable price, to "open the floodgates" to the less-in-need clients.
