Description

I am not sure that you are aware that users have made a patch for this feature, but did not report it here.
Patch: https://stackoverflow.com/a/77390012/5155484

I want the copy command to copy the modification time of my files so I am able to sync to S3 or other content providers files that do not have a changed date at each deployment.
This will allow assets to live longer on cached proxies, if the last modified date is not always changed.

That means that I can deploy like this:

• https://github.com/MestreLion/git-tools/blob/main/git-restore-mtime
• build Angular
• deploy

Describe the solution you'd like

Modify build-angular/src/utils/copy-assets.js async function copyAssets with an option top copy file stats

Describe alternatives you've considered

Applying the patch in a sloppy way

For context: What is the reason not to use ETag for the blob storage objects which isn't as sensitive to exact mtimes? Is it because support for it outside of S3 isn't always there?

Yes Etag is used on S3, but other deployments for example nginx will not have it
