Yeah, that is no reason for disabling plain HTTP, still. You have a
valid point with the unencrypted cookies though. I will probably fix
this when doing the next AUR release (which will be pretty soon).

Agreed. I'm still against completely disabling HTTP. We will use HTTPs
for all links by default so there shouldn't be any users unintentionally
pasting HTTP links anywhere. Malicious links might still be an issue but
observant users should be aware of that. And using secure cookies should
fix that, anyway.
