The ability to use functions from earlier versions of jQuery

I'm just thinking that it might be nice to be able to call functions from earlier versions of jQuery. Example: if a developer finds that his code worked in jQuery 1.4.4, but doesn't work anymore in jQuery 1.5.1 (or he finds a bug that wasn't present before), it would be nice if he could just use the code that 1.4.4 used. Such compatibility would be more useful if, on top of that, he wanted to play with features that 1.5.1 introduced to his development platform.

Quite often, when significant changes are made to jQuery core from version to version (especially in 1.x releases), those changes aren't just something that can be easily enabled to work with older versions of the library - they can be coupled tightly with other functionality, reliant on changes which break older versions but function fine with the newer updates etc. If someone wishes to use an older version of the library (we don't advocate/recommend they do) but they're free to if they need to use it on it's own. We don't however have the ability (to the best of my knowledge) to simply 'copy and paste' or enable newer stuff to work with older versions in a way that is both stable and consistently compatible, not do we have the resources to do so. I hope that addresses the suggested enhancement adequately :)
