Users' time is not free either.  When you make them set up
infrastructure, install programs, learn other tools, and so on, that's a
burden too, and I think it's dishonest to say only developers' time
matters.

You wanted use cases, you got them.  At this point your objection to
using more of the GnuTLS API seems to be "because I want FFI."  You'll
get it, and I'll work on it.  I just think FFI is the wrong way to bring
in the GnuTLS ciphers and hashes.

Please see my objection to loose coupling of encryption primitives in
particular.  They are not regular features and they won't change often
at all.  This is a very low-risk addition to the core.

Right.  Shelling out to an external binary every time you want to verify
a package's signature or want to encrypt/decrypt/sign data makes perfect
sense.

Blindly entering your passphrase in an anonymous popup that says it's
from the GnuPG agent is how things are done.

Trusting loosely coupled components is standard industry practice.

Forcing users to do all of that, or "no encryption for you" is for their
own good, on every platform where Emacs runs, from Android to W32 to Mac
OS X to many flavors of Unix.  Users are just too stupid to decide these
things on their own.

Is that how experts with a crypto/security background do it?  I'm
understanding now.
