Passing the empty string as an extension is a functional no-op, but causes actual problems: spf13/cobra#2228 Remove marking the flag as taking filename altogether, as there's no need to do that; cobra comments doing so as a mistake: https://github.com/spf13/cobra/blob/41b26ec8bb59dfba580f722201bf371c4f5703dd/completions.go#L387-L390 Leave MarkFlagFilename in comments so it's clear it's not inadvertently left out.

Foe example, current goreleaser (2.6.1) gives this

Arguably a bug to set an empty string there. Not sure if this should be filtered before it enters bash code, but at least this is a "cheap" workaround.
