There are probably extremely few instances where a name would rationally 
be reused; to do so for a different function would create chaos, not 
remove it. Or are you making the argument that some filters should be 
completely rewritten? (That could make some sense, but who's going to do 
it?)

There is a decent argument to be made in tagging some filters/etc as 
'deprecated'*, how those are chosen as a different question.

* use is discouraged, are not being maintained, might not work in all 
circumstances, etc
