Exclude node from cluster routing allocation

Hi ,

for a maintenance activity we exclude a node from cluster routing allocation. When a node get back UP, we were not sure how to remove it from exclusion so we simply include it by using following command
PUT /_cluster/settings
{
"transient" : {
"cluster.routing.allocation.include._ip " : "ip of the node"
}
}

Now our cluser/settings have both include and exclude for the same node. After some time we came to know that we can simply remove a node from exclude by passing the null using following command
PUT /_cluster/settings
{
"transient" : {
"cluster.routing.allocation.exclude._ip " : ""
}
}
This way we remove the node from exclude. but in our cluster/settings the node is still in include. does it impact routing allocation as we require to allocate shards to all node. if yes, is it safe to remove it from setting by passing nulll as below
"cluster.routing.allocation.include._ip " : ""

Thanks
