The problem isn't the long running transaction on the subscriber, but the one on the provider. Using multiple transactions for that means that the subscriber would not get one consistent snapshot of the entire set but rather a different snapshot for each single table. I think the first ever done SYNC is horrible enough as it is with its humongous where clause. I don't even want to imagine how that would look like if we had a different xid exclusion list per table in a 50+ table schema. Since we are now substantially speeding up the copy_set, I don't see how Slony is more of a problem than pg_dump.
