Actually, you can assign it to the root variable and use relative path.
You don't need parentheses in the root variable.

True. Variable expansion is broken. But you can use
set prefix=/grub/
That would allow you to load more modules as long as $root is unchanged.

This is broken for the same reason. But this would work:
search -s root -u XXXX-YYYY-ZZZZ-AAAA-BBBB

You understand it correctly. But the implementation is limited.
