Plugins, dynamic loading and GHCi

In SimplCore.lhs, addPlugin* is #ifdef GHCI. Is this dependency really 
necessary? plugins can be useful independently of the GHCi UI.

 From the wiki [1]:
  "Stage 1 does not support interactive execution (GHCi) and Template 
Haskell. The reason being that when running byte code we must 
dynamically link the packages, and only in stage 2 and later can we 
guarantee that the packages we dynamically link are compatible with 
those that GHC was built against (because they are the very same 
packages). "
This does not seem to be a reason to not support plugins and dynamic 
linking in general in stage though, or am I missing something?

Besides finding the dependency in this direction a bit strange, building 
stage 2 to debug plugin mechanism problems is a bit slow.
