[jQuery] Non-destructive jQuery

[jQuery] Non-destructive jQuery

Hi folks,
I'd really like to see John's modifications to pushStack included in the jQuery core. Details here: http://www.nabble.com/Non-Destructive-jQuery-tf2482924.html
I'm actually wondering if that modification would break any existing code, as end() works like before. I guess the only situation is in scenarios like this:
var jq = $();
var jq2 = jq.destructiveOperation();
var jq3 = jq.anotherDestructiveOperation();
With the non-destructive pushStack implementation, this would give a different result. Is someone actually using such code?
I think this modification is very important to improve the overall jQuery...
