This approach is used to advantage for Zope 3 schema. If you don't want to confuse the ordering, you don't re-use field objects (the things that go in schema). If you don't care about the ordering (because you're going to control ordering some other way), you don't need to worry about it. This is still Python; use what makes sense for your application, but know what you're doing. The "consenting adults" playground expects consenting adults to educate themselves.
