Sounds like he wants to weigh in on all his options more than being 'afraid' to do something. For instance I can't use mod_perl for a lot of my projects because the administrators of the servers the projects run on don't want it, so that's a consideration when picking modules, I have to pick ones that will run fairly fast even in a CGI environment, not because I don't love mod_perl but because it isn't always availiable.
