Putting aside the discussion on removing the support for non-POSIX
function names from Bash, as far as we support the other forms of
non-POSIX function names for « unset
'any-funcname-other-than-arr[index]' » and all the non-POSIX function
names for « unset -f 'any-funcname' », there is no reason that we do
not support « unset 'arr[index]' ».

I agree with this.
