Thanks for your contribution, unfortunately this would introduce a breaking change into an already GA feature in our client. We cannot accept this PR.

Hi @sydney-munro,

I don't think that this GA feature is of any use the way it works today. Whoever may be using this, they would need to expect that the destination files will be located mimicking the source directory structure (see my comment on #2573)

We could add some flag to enable this behavior, but I believe that this feature is rendered unusable because of this issue
