I personally don't like having specialized user mode daemons for things
the kernel can easily do by itself (which is the case here) Linux setups
generally already have too many daemons and they have some overhead,
another one should be only added for very good reasons.

The daemon would be only an excuse here for "we cannot work out a
sensible kernel policy" which would be bad.
