Why the switch? Gmail doesn't work in Safari 3.1! ( http://discussions.apple.com/thread.jspa?messageID=6856943 ) At least, not the Gmail I have on Apps For Your Domain, and it won't let me use the fancy, new one I have on regular Gmail sigh
Opera has had this feature for many years - I didn't switch to Safari until I discovered this plug-in.
Okay, I'm done venting now. Back to work sans 3.1...
edit: maybe 'entire OS' was a little vague. basically they don't want to run into issues where the webkit gets updated and things that rely on webkit don't get all messed up in the process because they are running too.
WebCore is a layout, rendering, and DOM library for HTML and SVG developed by the WebKit project, originally developed by Apple as a fork of KHTML. It is licensed under the LGPL. The WebKit framework wraps WebCore and JavaScriptCore, providing an Objective-C application programming interface to the C++-based WebCore rendering engine and JavaScriptCore script engine, allowing it to easily be referenced by Cocoa-based applications; later versions also include a cross-platform C++ platform abstraction, and various ports provide additional APIs.

basically it has to update and restart so that all cocoa based apps can use the new version.
