I have reviewed the v9 patch and my feedback comments are below:
//////////
1. Apply v9 gave multiple whitespace warnings
$ git apply v9-0001-Skip-empty-transactions-for-logical-replication.patch
v9-0001-Skip-empty-transactions-for-logical-replication.patch:479:
indent with spaces.
* If the BEGIN PREPARE was not yet sent, then it means there were no
v9-0001-Skip-empty-transactions-for-logical-replication.patch:480:
indent with spaces.
* relevant changes encountered, so we can skip the ROLLBACK PREPARED
v9-0001-Skip-empty-transactions-for-logical-replication.patch:481:

* messsage too.
v9-0001-Skip-empty-transactions-for-logical-replication.patch:482:

warning: 4 lines add whitespace errors.

2. Commit comment - wording
pgoutput will also skip COMMIT PREPARED and ROLLBACK PREPARED messages
for transactions which were skipped.
=>
Is that correct? Or did you mean to say:
AFTER
pgoutput will also skip COMMIT PREPARED and ROLLBACK PREPARED messages
for transactions that are empty.

3. src/backend/replication/pgoutput/pgoutput.c - typo
+ /*
+ * If the BEGIN PREPARE was not yet sent, then it means there were no
+ * relevant changes encountered, so we can skip the COMMIT PREPARED
+ * messsage too.
+ */
Typo: "messsage" --> "message"
(NOTE this same typo is in 2 places)
