The case that matters for me is the Bash that ships with "Oracle Linux".
Which turns out to be version 4.2.46(2) from 2011, which is a lot older
than I would expect. But it *does* cause an error in that verison:
$ ( set -u ; FOO=() ; echo "${FOO[@]}" )
bash: FOO[@]: unbound variable
$ bash -uc ': "${FOO[*]}"'
bash: FOO[*]: unbound variable
$

It looks like that's a change since 4.2.46. Is there text in the manual
page about that?
