Its such a simple exercise for the race organiser

That really depends on what the organiser currently does. Organising a race consists of lots and lots of simple things. If we start demanding more, it might put future organisers off.

as you get older ( 55 60 65 etc) your fitness, ability etc is more difficult to achieve/maintain so a closer comparison is essential.

Essential?? At these ages (which includes me) it's just nice to be able to take part in a race - anything else is just icing on the cake.
