In Shopware 5, it was possible to pass additional configuration to the S3 adapter in order to add custom headers during media transmission.

Currently, this is not supported, and I haven't found any relevant documentation on this in Shopware. Our current workaround involves setting the headers recursively once a day using a cron job.

Therefore, the first idea is to enable the transfer of additional headers in the S3 adapter.

Moving on to the second idea related to the same S3 adapter topic, it would be incredibly beneficial to have a configurable read/write mode. This is important for every developer. When setting up a new shop, all I need to do is check out the project, import the database, and directly use the images from the live S3 bucket through S3 configuration. However, it should not be possible to delete or overwrite the live images from the development machine.
