It was rejected upstream previously a few times.

If we want it, it has to be a patch on upstream in our gpg version.  I
believe the reasoning that allowing larger key sizes are a performance
issue for mobile does not really apply here.

Even gpg 2.1. dev is still limited to 4096:
Line 1943, max=4096:
