I am trying to understand Example 2 in the Incremental Processing documentation:
<https://kotlinlang.org/docs/ksp-incremental.html#example-2>

I don’t understand the following statement:

&gt; When `sourceA` is removed, nothing needs to be reprocessed.
Why is this the case? If `outputB` is aggregating then _changes_ in `sourceA` will mean reprocessing but why not _removal_ of `sourceA`?

note that “An aggregating output can potentially be affected by any input changes, except removing files that don’t affect other files.”
