[SalesForce] Are Duplicate Rules Supported by Metadata

I've found how to reference Matching Rules by name in Metadata, but that's only the logic to identify a duplicate. I'm looking for how to reference Duplicate Rules by name in Metadata, which will dictate what to do when a duplicate is found.

Does anyone know if it's supported in Metadata yet, and if so what's the name to reference it?

XML from retrieving

<types>
    <members>*</members>
    <name>MatchingRule</name>
</types>

<MatchingRules xmlns="http://soap.sforce.com/2006/04/metadata">
<matchingRules>
    <fullName>Custom_Contact_Rule1</fullName>
    <booleanFilter>((1 AND 2) OR 3 OR 4) AND 5</booleanFilter>
    <label>Custom Contact Rule1</label>
    <matchingRuleItems>
        <blankValueBehavior>NullNotAllowed</blankValueBehavior>
        <fieldName>FirstName</fieldName>
        <matchingMethod>FirstName</matchingMethod>
    </matchingRuleItems>
    <matchingRuleItems>
        <blankValueBehavior>NullNotAllowed</blankValueBehavior>
        <fieldName>LastName</fieldName>
        <matchingMethod>LastName</matchingMethod>
    </matchingRuleItems>
    <matchingRuleItems>
        <blankValueBehavior>NullNotAllowed</blankValueBehavior>
        <fieldName>Email</fieldName>
        <matchingMethod>Exact</matchingMethod>
    </matchingRuleItems>
    <matchingRuleItems>
        <blankValueBehavior>NullNotAllowed</blankValueBehavior>
        <fieldName>Phone</fieldName>
        <matchingMethod>Phone</matchingMethod>
    </matchingRuleItems>
    <matchingRuleItems>
        <blankValueBehavior>NullNotAllowed</blankValueBehavior>
        <fieldName>AccountId</fieldName>
        <matchingMethod>CompanyName</matchingMethod>
    </matchingRuleItems>
    <ruleStatus>Active</ruleStatus>
</matchingRules>

I would expect to be able to retrieve Duplicate Rule data as well, which specifies the following pieces of data

• If sharing rules are enforced
• If users can bypass the creation on create or edit
• How the fields are mapped
