I did work on one scheme that uses OpenPGP and I did some extensive 
tests even before was announced and in terms of 
reliability it's day vs night compared to SKS.

Hagrid, as far as understand it, serves keys from static files so it by 
design has good performance. SKS on the other hand requires caches in 
front of the server and, in my tests, it was frequent that an old 
version persisted in the cache long after I updated a key.

No such issues on, gpg --send-key and the new updated 
key is immediately available with no time outs or delays.

Decentralized non-identity information hagrid could still be possible. 
It's just a question over which protocol to synchronize this kind of data.

Kind regards,
