W3C Zoom CSS property. I really want this feature included!!!

Lot's of people are discussing this.
And the designers are often saying something like:
"I cannot imagine a scenario where you will need to use the Zoom CSS property."
To the readers that haven't yet hit this problem - the CSS Zoom property seems to be proprietary and to be working for IE (I think version 6 and above).

To all those designers - there ARE scenarios where you will want to let the user zoom everything proportionally without using the browser buttons / sliders / shortcuts, but with CSS / JS only.
I will give you few examples:

1. I needed to create an overview control of page. It should represent the page in a smaller percentage and, upon scroll, the page should scroll proportinally. I can have a div with the same DOM tree (or even an IFrame loading the same page or something). In this case I URGENTLY need the CSS Zoom property.
2. Telerik radReporting - the ReportViewer has a dropdown to let the user choose a zoom level to preview the page (web based and not after clicking print preview or something). Actually the Print Preview browser command isn't an option as the report viewer may be on the page with other controls and the user SHOULD BE ABLE to zoom in and out only the portion of the page where the report is (it is an IFrame with the data rendered as HTML, I believe). In telerik case - there seems to be some browser detection and when the browser isn't capable of zooming in / out - the dropdown with the zooming levels is simply hidden (they have no other choice unfortunatelly and I support them for this decision).

Now, as you may expect - in my scenario I cannot simply hide the overview control as the page heavilly depends on it.
Should I now have my revenge now? I've seen all those messages accross the web telling you that there are better browsers to use than IE.
Should I now display a message like:
"Sorry, your browser isn't capable of zooming in and out, only IE supports this, so please switch to IE."

I really hate those browser wars and if you really want to know my opinion - yes, IE may be harder to design. It may be messing up the containers, it may not be passing the ACID N test.
But it is the only browser that is suitable for my scenario (at least from my search in IE all the posts were following the same line - "zoom is IE proprietary, it won't work under other browsers").
Why are all other browsers sleeping then?


P.S. I have found something like -moz-zoom or something but wasn't able to make it work under FireFox (if it works under Firefox it should also probably work under Google Chrome as they are using the same engine I think).
P.P.S. - haven't tested but I think the zoom CSS property should also be available under Opera as they (as far as I know) use the IE core.

P.P.P.S - if anyone know how can we ask W3C to reconsider this for at least the next revision of CSS I would be glad to give my vote. I also advice telerik to do the same. Not only the reporting will work in all browsers but they may be able to do some other great controls using this property.

Really annoying ...
