Yes, I've just reported it to GnuPG: https://dev.gnupg.org/T6481.  Let's
see what they say.  

There's --command-fd option which allows to separate command input from
data input, then we perhaps can avoid waiting for BEGIN_ENCRYPTION
before sending data.  But I don't know how to use it from Emacs side: we
need something resembling coreutils's mkfifo, which we open for writing
in Emacs (like a process), and pass it's fd to gpg.  I'm not expert in
these things.

Maybe someone else here has ideas.

Filipp
