Some of the better alternatives don't even _try_ to run milters, because
they are fully-featured enough in their own right, without needing to
rely on external software.

Which means that you can't run your choice of tests on a message during the smtp conversation before you accept it - at least without starting a new process for each one which is expensive for large programs like spamassassin. And if you accept a message but don't deliver it, you are supposed to generate a bounce to the sender, but that is always the wrong thing to do if you think it might be spam or a virus. Running your checks in time to do an smtp reject eliminates that problem.
