Installing HP should not get in the way.  I suppose that, even if installing HP doesn’t get in the way, it might be a waste of internet bandwidth and disk space for some power users.  But that is a smaller problem.

I’d say, both. 

Re 1, a big part of the problem is the whole cabal, package dependency and versioning morass. 

Re 2, I think, there are multiple factors. The delays in putting out the HP (as previously mentioned). Power users reading GHC Status reports and wanting to get the goodies as quickly as possible. The HP just being quite a bit of hard work people like to avoid.
