You have to start somewhere with security.

I think that an uploaded trojan library would be at least detectable as 
such, since the uploading user would have change (i'm not sure that what 
you had in mind ?).

Whereas on a mirror, it would be completely transparent to the users.

As a first step, having the hackage server and its users trusted, is 
hopefully reasonable. And then you can build up from there. This would 
be nice to be proactive before we actually detect such a thing, and we 
have to build a security infrastructure anyway ;)
