I cannot see how this solve a situation I had in mind. What I am refering
to is: I create a new filter which I know should be executed before filter
A, but after filter B. The filter is written much later then any resource
serving my files. So, how would I make resources know in which order to
execute my filter? Would I have to go and edit each resource? Would they
have some generic algorithms built in? I just don't see how it would
happen.

Maybe I don't understand something and I can wait until release to see how
it works, but I felt that a bit more flexibility in filter execution order
would be only for the advantage without bringing any harm(?).

With all due respect,
      Alex.
