Are you asking that I remove the qualifiers, or just pointing it out?  I'm happy to remove them.  

Other than extra space, is there a disadvantage to qualifying the functions?

In head-less things like internal package code, I've always thought it was a safer practice to qualify the the function names, so that it wouldn't inadvertently call the wrong package.  Even if you know the current set of packages wouldn't conflict/collide, problems could occur with future additions to those imports/depends packages.  

I guess it's a smaller issue now that it was a year ago, when we had to worry about the packages imported by our imported packages.
