I'm not sure I understand what you are proposing as an alternative
here. Should we stop shipping ca-certificates? Or make it a binary
package of the NSS source package?

I don't understand this: how is it incorrect? #858539 applies only to
ca-certificates, and can be fixed without patching NSS.
Now to update the NSS package itself is another question, again.

Sure, but that doesn't necessarily affect ca-certificates directly, in
that we can update ca-certificates orthogonally right now.

Sure. The point I was trying to make here was that we seem to be
favoring certain well-known CAs over other less well-known. I'm actually
with that (e.g. because I don't like Amazon very much), but I'm not sure
that's a position that should be reflected in our work.

I can't answer those questions, unfortunately, but it's a fair point.
Pabs? What was the idea behind migrating LE down to wheezy?
