I haven't looked at much of this PR, but I did spot one problem. If a new method really is needed in the InputMethod interface, you will likely need to make it a default method to avoid compatibility issues. In any case, this requires a CSR.

I'd like an extra pair of eyes on this. Also, as noted above, it will need a CSR.

Oh, I see that Andy already requested a CSR. Thanks!
