Too many repos?

[David Jencks]

I've noticed that my builds seem to spend a lot of time looking at non- 
standard repos such as apache m2-incubating, the often disfunctional  
java.net m1 repo, codehaus snapshots etc etc.  I'd like to suggest  
that our main project poms not include any repos at all -- the apache  
pom defines maven central and apache.snapshots -- and that if we  
really need one of these repos for some plugin we include it in that  
plugin's root pom.

thoughts?
thanks
