Xeroc rejected the BSIP without interacting with the Bitshares network/community, even the 'deferred' status is not justified. I believe it may be because the "BTS Foundation" is focusing on regulations specifically bending over backwards for Bittrex (which good riddance at this point tbh..).

The UIAs can be distributed through a python script using the python-bitshares library, so I'm less concerned about that as I am about implementing this functionality for MPAs.

Are you interested in seeing this BSIP implemented?
