R2 also makes it hard to figure out how to simply upload a file.

In both S3 and R2, it would be relatively easy to create an client/overlay that has a similar interface to TFA.

The syntax is a bit obtuse, but you setup creds and then:

    wrangler r2 object put test-bucket/file --file=file

Yeah, but now try uploading a folder. They'll just refer you to their S3 API. Also, that's 4 levels of commands, it's more than my mind can easily remember.

aws s3 sync [source] [dest]
