bugzilla.redhat.com vs upstream bug trackers

[Florian Weimer]

I'm wondering what the current guidelines for filing bugs on 
bugzilla.redhat.com are. 
<https://fedoraproject.org/wiki/Bugs_and_feature_requests> welcomes 
filing enhancement requests, but some package maintainers disagree and 
require filing bugs upstream.

I would like to avoid creating accounts in gazillion upstream bug 
trackers, so bugzilla.redhat.com as a single point of contact is very 
helpful to me.  Is the web page I mentioned outdated, or are package 
maintainers expected to handle upstream bug tracker interactions?
