deno write/stor media file on deno deploy

Problem
One of probleme with serverless/edge platform that they doesn't support writing in file system  for example let's imagine if I develop/write web app that allow client to upload file then I store file reversed by client using Deno.write API ( to be sure  I test my app in local and all tests passed 100 %) then I want to deploy my app in deno deploy (or similar) I must update my ts code to store file in s3 (or equivalent )
I aime to have possibility to deploy this app on deno depliy without change my code

Solution proposed
I think it will be usefull to support async Deno.write  API in deno deploy payed plan(I know it not exist yet). under the hood deno deploy can use s3 or equivalent this will minimise neede to change/config code when ready for production.
N.B
we understand write not supported in deno deploy for security perpose ... and there are service dedicate for this like s3

No files, tests, or entry points are named in the issue. Start by reviewing how Deno.write is supported or restricted on Deno Deploy and the proposed storage behavior, then define the scope and acceptance criteria for a compatible persistent write API.
