Multiple Site Alias request returns insufficient error content

In setting up some tools to 'bulk-manage' site aliases, it appears that when I make a request to get Info for multiple Site Aliases and one of them doesn't exist, I get a generic, singular, and somewhat malformed result. Examples below:

There were four aliased subdomains on qa.domain.com. The last two aliases have been removed prior to this test.

REQUEST

<packet>
    <site-alias>
        <get>
            <filter>
                <name>alias-02.qa.domain.com</name>
                <name>alias-03.qa.domain.com</name>
                <name>alias-04.qa.domain.com</name>
                <name>alias-05.qa.domain.com</name>
            </filter>
        </get>
    </site-alias>
</packet>

RESPONSE (in JSON for readability)

{
    "success": false,
    "domain": "..domain.com",
    "message": "Domain alias does not exist"
}

The domain element is malformed, and it neither gives me the info that it can get on the existing aliases, nor does it tell me which aliases, if any, do not exist.

I can work around this by making discrete calls to see which fail, but cringe at the wasted overhead and time to set this up.

Start with the multi-name site-alias get request and its malformed response example, then trace how the library handles missing aliases and successful results. Done means the response identifies missing aliases and returns information for aliases that exist, without the malformed domain value.
