I’m a complete outsider here.  The only reason I’m subscribed is because 
I once had to ask a question, which uncovered a rift that, from the 
outside, looked thus: an entire community on the one hand (OpenPGP), and 
on the other hand the 800 pound gorilla (GnuPG).  Unlike any other 
implementation, we can’t ignore what GnuPG outputs by default, and we 
can’t output anything it cannot decode.  Which gives you, Mr Koch, a 
rather unique ability: bending the world to your will.

Using that ability tends to breed resentment though: every time you 
diverge from the rest of the world, every time they change something 
*and you don’t*, more people will wish they could break free from 
GnuPG’s hold.  (For full disclosure, I already do.)

And today I learn that on the upcoming post quantum support, there will 
be *another* divergence between OpenPGP and LibrePGP?  Unless you can 
argue urgency, and everyone believes you, this will breed more resentment.

Good.  Avoiding a third rift sounds reasonable.

Loup.
