   Yes, that's the kind of application where it's a problem.  You attach GPIOs   
   to random stuff and intend to probe what's there.  That means you flip   
   through the internal settings for input/output/pullup/pulldown and listen   
   out to how the input changes.   
      
   The leakage affects that kind of application badly (input pins should be   
   high impedance but they aren't here) but if you are putting the chip in a   
   board where you already know what's on the other end of the pin, you can   
   design the circuit appropriately.   
      
   RPis are more likely to be used in situations where you take the MCU and   
   plug in and out random things onto the pins which are affected by it,   
   compared with other MCUs where they only ever get put on vendor PCBs where   
   everything is predetermined in the schematic.  So it's really a hobbyist   
   focused problem rather than a wider problem.
