This has been proposed many times and the past and has been rejected  
so far: the point of the filter system is to translate markup. In  
order for it to work in all situations, it must be agnostic about its  
context.

Sure, some things could be hacked in if we pass in a node or comment,  
but there are already other mechanisms in place that are much better  
for this. Nodeapi offers plenty of opportunities for altering nodes,  
especially now that node output is structured.
