Another 5G Wrinkle

So for the last several days, the several flights out of KEYW, Key West, destined for the Northeast (EWR or LGA) have flown a short distance to other southern Florida fields (RSW, MIA, FLL, MCO OR PBI) to take on more fuel before continuing the flight to its destination. These are all E170 flights flown for UA and DL by Republic Airways. KEYW has a short runway at 5,076 feet.

I understand the reason for limiting takeoff fuel weight has to do with the E170 EICAS logic which inhibits certain warning messages below 400 feet AGL as judged by the RA. Because of possible 5G interference with the RA, these inhibited messages may appear on the takeoff roll causing confusion. Since one of the potentially no longer inhibited message has to deal with brake failures, so to deal with that worst case RTO scenario,, takeoff weights are significantly reduced!

Who thinks this stuff up? And why is the 5G band an issue at Key West if it has allegedly been disabled near airports?
So far, the 5G interference issues seem centered around stations with CAT 2 and CAT 3 ILS approaches. The 5G is probably still operating at Key West because it doesn't even have an ILS approach .

Are there other issues having to do with potential 5G interference unrelated to advanced ILS approaches?
