"API" as service?

I have been reading into the whole web3 world recently. It got me wondering, do we see a future where common functionalities are abstracted and made available as a service? Different apps/ products using the same contract or set of contracts or a "service" for their core functionality. This way they get more security of a bigger chain, easier scalability option based on the requirement of the app, up tp date vulnerability fixes etc, etc. Different apps can customise their specific app based on their requirement.

For example:
"A generic social media service"
Any "client" can have a smart contract or a frontend app that can use this service which provide basic functionalities such as messaging, ability to create posts, groups , ability to incentivise participants(users of app) with tokens/ coins. The "client" smart contract can create its own coin or rewarding system and rollup it's data on the service chain.
The service chain itself can be a rollup chain to Ethereum. It should also be deployed on various other chains so that the client can choose different scalability/ migration options for their business.

Do we see a future like this of "API as service" in the web3 world? Or the classic web2 kind of development where each product deploys its own "code" on cloud?
