No. I'd use nodes for configuring Servlets and Filters and have a
mechanism in the Sling framework for mapping those configuration nodes
to the runtime instances of the components they represent.

For example, instead of having "filter.scope" and "filter.order"
properties associated with filter components, I'd rather put that
configuration information inside the repository, as sling:filter nodes
within a configuration subtree. Something like this:

                filter1 [sling:filter]
                filter2 [sling:filter]
                filter3 [sling:filter]
                filterA [sling:filter]
                filterB [sling:filter]

This way you could use normal JCR editing tools for configuring and
modifying the application. Even better, with scripting support the
filter nodes could even be nt:files (or contain nt:files) with the
actual filter script that you could then modify in-place.
