If existing software applications only set the DSCP values when the user
asked, it wouldn't be as much of a problem. However some software
programmers gratuitously set DSCP/TOS values even when the user didn't
want it.
If you drop packets from unauthorized DSCP/TOS users you will break many
applications for users which are unable to change the behaivor of their
application.
On the other hand, if you clear DSCP/TOS bits from unauthorized users
you will continue to provide basic service for those users.
Which is better?
Dropping the packets with unauthorized DSCP/TOS bits?
Forwarding the packets with cleared DSCP/TOS bits?
