You must remember that at places like Gatwick where ATC and the aerodrome authority are different, it is the aerodrome authority that send NOTAMs concerning the airfield, as they are obliged to do under their aerodrome licence. You may not be interested that stand 11 is out of service but operators at Gatwick would be.
And as an ATCO I wouldn't want a pile of information on my desk that I have to read out to pilots, nor would we want it on the ATIS. No, a NOTAM is the correct place so that pilots PRE-BRIEF.
