Getting people to update max-version retrospectively is the problem. 
That's essentially why IE User-Agent strings spoof Netscape, and why
everyone else, including Netscape(!) spoof IE, in the comment that 
contains IE's real identity.

Basically what happens is that the user agent gets updated to remove a 
restriction, but the legacy web pages (and those cut and paste coded 
from them) still effectively reject it.  The result is that the browser 
has to spoof the market leader to get round this.

The original CSS concept was that unsupported properties were simply 
ignored, so that they would automatically start working when the browser 
starts supporting them.  I know this makes pixel perfect designs difficult.

that is no longer good advice, as archive address hiding may not work.
