I did that in my first draft and I found it confusing.

Each filter has 3 parts (some filter-specific data structures,
a filter callback routine, a driver to call the traverse code).
I found it easier to reason about each filter in isolation.
And it makes it easier to work on each independently and keep
their inclusion in separate commits.
