Monarch Man,
I do know this argument is about MAN 24L/R. But according your own words you feel its wasted airtime to mention established 24R. Because, again according to your own words, you can't be established on 24L as it has no ILS.
With that logic in mind can you explain to me which R/T procedure you use in LGW? Technically you can't be established on 26R as it has no ILS. But the last time i listened everybody used 'established 26L'. Even our own company aircraft.
If you feel its required in LGW, why do you think its not required in MAN?
