Narrowly, I don't think there's any technical reason why a better clipboard couldn't require the user to specify where to send text ("paste content into application X field Y") and then handle transmitting that data on the user's behalf. That way, the clipboard wouldn't be readable global state without intent. The paste intent doesn't seem antithetical to accessibility. A keyboard combination states intent just as effectively as a voice command, mouse input, or other source.
