 a perfect world. PHP 5.3 offers solutions to problems that aren't fixable
 in 5.2, name spacing being a major example. They weren't added on a whim.

 use of a library that was built with 5.3 in mind?

 Namespacing isn't something a plugin needs. It's helps you out to
 structure code. So it's not naive thinking when you can make the plugin
 working on 5.2 by not using namespacing. It wouldn't work less.

 Libraries is indeed an issue and I also sometimes use them. However I
 would never release the plugin on .org.
