"etcupdate -p" vs. $OLDTREE?

After the set of updates to etcupdate (main-n246232-0611aec3cf3a ..
main-n246235-ba30215ae0ef), I find that "etcupdate -B -p" is working as
expected, but after the following "make installworld", a subsequent
"etcupdate -B" chugs along for a bit, then stops, whining:

No previous tree to compare against, a sane comparison is not possible.

and inspection of the $WORKDIR before:

freebeast(14.0-C)[1] ls -lT /var/db/s4/etcupdate/
total 260
-rw-r--r--  1 root  wheel       0 Apr 22 05:17:54 2021 added.files

-rw-r--r--  1 root  wheel       0 Apr 22 05:17:54 2021 removed.files

and after (the "make installworld"):

freebeast(14.0-C)[2] ls -lT /var/db/s4/etcupdate/
total 36
-rw-r--r--  1 root  wheel     0 Apr 23 03:53:41 2021 added.files

-rw-r--r--  1 root  wheel  8556 Apr 23 03:53:41 2021 old.files
drwxr-xr-x  5 root  wheel   512 Apr 23 03:53:41 2021 preworld
-rw-r--r--  1 root  wheel     0 Apr 23 03:53:41 2021 removed.files

shows the lack of a "current" subdirectory.

After invoking "etcupdate extract", then "etcupdate -B":

freebeast(14.0-C)[3] ls -lT /var/db/s4/etcupdate/
total 260
-rw-r--r--  1 root  wheel       0 Apr 23 03:58:59 2021 added.files

drwxr-xr-x  2 root  wheel     512 Apr 23 03:58:59 2021 conflicts

Am I missing something?

Thanks!

Peace,

The same folks who champion the "rights" of corporations to influence
elections by money (as an exercise of free speech) are now also decrying
corporations' speaking out against voter suppression laws...?  Right.
