The comments have been addressed, and the patch also resolves a
limitation where sequence parameter changes between creating or
altering a subscription and sequence synchronization worker syncing
were not detected and reported to the user. This issue is now handled
by retrieving both the sequence value and its properties in a single
SELECT statement. The corresponding documentation also was updated.

The attached  v20240814 version patch has the changes for the same.
