Specifically, it undid this change:

(The addition of the #include <vm/vnode_pager.h> from this commit remains as
a local diff in main FWIW)

It looks like vnode_pager_clean_*sync() are thin wrappers around
vm_object_page_clean() still in main, but I'm curious if this change
needs to be kept in main and/or upstreamed?
