If the subscriber gets a bit of logic to say "Something went wrong, so I'm automatically stopping what I'm doing", it sounds logical to give the publisher the same ability.
The wording for that option is:
Specifies whether the subscription should be automatically disabled if any errors are detected by subscription workers during data replication from the publisher.
A subscription worker has no clue what the publisher is doing. It operates on the “when I see data I act on it” model.
As for whether the publisher should have this clause - the errors in question are logical, data-oriented, errors, which the publisher is incapable of having.
I believe what you are effectively requesting is that instead of disallowing updates and deletes on the added table that lacks replica identity you wish for the addition itself to fail. That would have made a better default behavior with an option to override when the current behavior is desired. But it seems too late to change this decision now.
