But echo does not "return" the string as a value.  It outputs the
string.

To quote the man page for bash, "the return value of a simple command is
its status".  Further, a function does not actually return any value
beyond the status of the last command or a value given on a =return=
statement.

I disagree.  I think the current behaviour (i.e. before your attempt to
"correct"" this) is correct given the documentation you quoted!

Common?  I have no idea.  *I* did expect this.  But that's maybe because
I do use the shell a lot.

I think there's a clear distinction between value and output for src
blocks and blurring this distinction for shell src blocks would be
misleading.  The option to request the output as the outcome of the src
block is already there.
