kv.lock.exclusive_locks_block_non_locking_reads.enabled dictates whether exclusive locks block serializable non-locking reads. It defaults to true for compatibility reasons, but we'd like for it to default to false (and then be removed).

To address this, we'll likely need to address #91417 first to avoid regressions in workloads like YCSB.
