I would love to extend Craft with a custom AssetSourceType. However it looks like components of type 'assetSource' are not extensible (enableForPlugins = false).
Is there a way to do this?
Or can I simply swap core services in the
common.php without hacking the core?
My goal is to provide a 'S3CompatAssetSourceType' - the main difference to the S3AssetSourceType is the API endpoint.
