The behavior is the same for the explicit INCLUDE publications as
well. For example, dropping and re-creating tables won't make it part
of publication automatically.

postgres=# create table inc_t(c1 int, c2 int, c3 int);
CREATE TABLE
postgres=# create publication pub_inc for table inc_t;
CREATE PUBLICATION
postgres=# select * from pg_publication_tables;
pubname | schemaname | tablename | attnames | rowfilter
---------+------------+-----------+------------+-----------
pub_inc | public | inc_t | {c1,c2,c3} |
(1 row)
postgres=# drop table inc_t;
DROP TABLE
postgres=# create table inc_t(c1 int, c2 int, c3 int);
CREATE TABLE
postgres=# select * from pg_publication_tables;
pubname | schemaname | tablename | attnames | rowfilter
---------+------------+-----------+----------+-----------
(0 rows)

You can see after drop/create, the table is no longer part of
publication. The same happens for the EXCLUDE case, so I don't see the
need for additional docs to explain this behavior. OTOH, if this
behavior was not obvious to you or you got some such question from the
users of this feature then feel free to propose a docs patch.
