Hmmm... either produces the same results for this simplistic example, but
yours works for more complex examples.  Guess this doesn't do exactly what I
thought it did.

Still not quite right.  Here's the full test script I'm using to illustrate:

#! /bin/bash
function doit()
{
   let idx=$#
   set "\"${@:0:$idx}\" new-value"
   echo "$@"
}

doit "foo bar" widget
doit one "two three" four

This produces the following results:

"foo bar" new-value
"one two three" new-value

If this is to be passed on to the next command the results would instead
have to be:

"foo bar" new-value
one "two three" new-value

So there's still some quoting issues.
