The filter system has always been context agnostic: it takes text and 
marks it up. This is intentional, mostly because it ensures it only 
deals with actual markup and styling, and not features.

Implementing contextual filters goes well beyond passing in a $node 
parameter. What happens for example when you edit a node? How is the 
filter cache keyed, and do we wipe it selectively? Do we provide 
contexts for other things than nodes too?

You can already modify node content using nodeapi before viewing. The 
only downside is you don't get it cached through the filter cache.
