Perhaps a handy little kernel warning on first use of a /dev/cuaxx (a la broken flock), along with some Documentation describing exactly _what_ is wrong is the cua devices, _why_ the tty devices should be used instead, and _how_ programs should be converted to do this. Without that sort of documentation, a conversion like this isn't much fun, or very fair to the folks who just use the things without understanding them.
