Using "-overwrite" to opt-in to overwrite an existing file looks good to me.

The CSR still has wording to suggest that the new option is also to support socket/other files. I read the PR as just the overwrite existing file case. If so then maybe those (two) sentences can be changed in the CSR to make it clearer.
