32768-bit key

First, come up with a reason why you need one.

A 2048-bit key is hypothesized to possess about 112 bits of entropy; a 
3072-bit key, about 128; a 16k-bit, about 256.  You very rapidly reach a 
point of dramatically diminishing returns.  A 32k key gives you 
essentially nothing in terms of resistance to cryptanalysis, while 
making it impossible for the rest of the OpenPGP ecosystem to work with 
you because your public certificate is so unreasonably large.

I suggest filing a bug report with them and asking them why they ignore 
the best practices of cryptography.
