Chivers:
I've never thought of Roses as being unsafe, they seem fine until people start trying to terminate more cables into them than their design or do you mean working on them at height?
Most modern light fittings are designed for a ceiling with just one cable. Rarely is a terminal strip incorporated in order to replicate the terminals in a ceiling rose. Therefore the installer ends up having to use a chocolate block to make the connections. More often than not there is insufficient space in the light fitting to contain the chocolate block so it ends up being shoved into the ceiling cavity with exposed live parts. A very shoddy and potentially dangerous arrangement.
There is also the controversy of a permanent live terminal in a ceiling rose.
