Template "If the result is an empty string, then the file is removed." can i keep the old file instead?

when a template get executed I noticed that "If the result is an empty string, then the file is removed" is there a way to allow the old version exist when the output of the template is empty string ?

The best approached I found was

{{- $targetFile := joinPath .chezmoi.homeDir "folder" "file_name" -}}
{{- $fileInfo := stat $targetFile -}}
{{- if and $fileInfo (gt $fileInfo.size 0) -}}
{{-   include $targetFile -}}
{{- else -}}
{{-   template "file_template" . -}}
{{- end -}}

You could also use a modify_ script or a modify template for this.
