While it's probably rather presumptuous for any of us to speak on behalf of 
everyone, my own opinion is that it probably depends on the environment. For 
example, when using a desktop or laptop I believe the expectation would be that 
they all work together and that none of them precludes the use of the others. 
In other words, connecting a braille device which has a keyboard shouldn't 
disable the computer's keyboard.

This is a different issue. My guess is that the very same thing happens if 
you're using a Bluetooth keyboard with iOS. The issue, in this case, is screen 
usage. An on-screen keyboard consumes a fair amount of the area of the screen 
on a small device. These platforms, therefore, tend to be designed so that half 
(or maybe even more) of the screen isn't hidden by an on-screen keyboard if an 
external keyboard is connected.
