"Most people" barely know what a subshell is.

My personal opinion is that this is horrible code and you should be
ashamed of it, if you wrote it.  The return is executed in a background
job, so it does nothing except cause immediate termination of the job.

I don't see any compelling argument to change the way Bash handles this.
