Time passes, and now on NetBSD-9.0:

NetBSD slave 9.0_STABLE NetBSD 9.0_STABLE (SLAVE) #2: Thu Jul 23 10:33:30 AEST 2020  stix@slave:/home/netbsd/netbsd-9/obj.amd64/home/netbsd/netbsd-9/src/sys/arch/amd64/compile/SLAVE amd64

find: /home/netbsd/current/obj.amd64/home/netbsd/current/src/sys/rump/fs/lib/libext2fs/ext2fs_balloc.po: No such file or directory
find: /home/netbsd/current/obj.amd64/home/netbsd/current/src/sys/rump/fs/lib/libext2fs/ext2fs_vnops.pico: Bad file descriptor

Directory hasn't been modified since ~May, so the only updates are
likely to be atime touches by backups, /etc/security, etc.
