Should we ignore some keys (like arrow keys?)

[nsg]

Hushboard have been useful, and it has been really nice to just hammer away on the keyboard without worring about the noise. Today I accidenitly muted myself when I was talking with a colleague. I never really speak and write at the same time so that "just works for me" but this time I did not really "type words", I was using the arrow keys to navigate an application.

The question is, should we ignore a few keystrokes like the arrow keys? Will this open the can of worms of requests of keys to ignore? Should this feature exists? I'm still not sure what I think, I just know that for me, today, it would have been useful for me to have the arrow keys ignores.
