Note that due to technical details, the new macros will reject uses with zero
variadic arguments. In such cases, you will want to continue to use the
zero-numbered macro, e.g. NS_IMPL_ISUPPORTS0(nsFoo).
I can't help wondering who would need to implement only nsISupports. It
can't be for the refcounting, because you can just use inline
refcounting. And you've got no way of telling whether an arbitrary
nsISupports is your object or not.
For example, nsMemoryReporterManager creates an object, hands it out,
and assumes the one it got back was the one it handed out. (I picked
that as an easy example that could technically be written safely using
an nsSupportsPRInt64.)
