I think the results can be processed through methods such as `printf %q` or
`"${result@Q}"`

Would it be unreasonable to expect that the argument to the outermost echo

That way, the line would be evaluated the same way as it would've been without
M-C-e.
Double-quoting is probably the way to go in that case, but then the M-C-e logic
has to also be smart enough to backslash escape things so the line gets
evaluated the same way as it otherwise would've been. And single-quotes should
be left in place as well.
$ var='foo'
$ echo "$( echo '${var}' )" # enter
${var}
$ echo "$( echo '${var}' )" # M-C-e
$ echo ${var} # enter
foo
# Would've expected: echo "\${var}"
$ echo $( echo '${var}' ) # enter
${var}
$ echo $( echo '${var}' ) # M-C-e
$ echo ${var} # enter
foo
# Would've expected: echo \${var}
$ echo '${var}' # enter
${var}
$ echo '${var}' # M-C-e
$ echo ${var} # enter
foo
# Would've expected: echo '${var}'
$ echo "${var}" # enter
foo
$ echo "${var}" # M-C-e
$ echo foo
foo
# Would've expected: echo "foo"

Doesn't list quote removal.
