Clean Prototype fork (good idea?)

Is there a prototype fork that doesn't come with any DOM/ajax parts? I really prefer jQuery for these, and would rather not carry the extra baggage. So far I've been using the excellent JS.Class library, which doesn't even touch b开发者_StackOverflow中文版uilt-in classes prototypes. However, I've been outgrowing its capabilities, and prototype would fill its holes.

The biggest issue is: how bad is for a library to require prototype? Even such clean one (without the dom helpers, such as $ and $$).

It's not out yet, though.
