 work on every WordPress installation. That to me does make a plugin good
 or not. Obviously stuff added to 5.3 and 5.4 is cool to use.

 and that is a performance penalty.

 This is naive, while we'd like this in a perfect world, we don't live in 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.

 What's more, other libraries that a plugin might require weren't built for
 WordPress. What if I built a plugin that by its very nature required use
 of a library that was built with 5.3 in mind?
