Is it possible request methods to existing sObjects to Salesforce?

How difficult would it be for Salesforce to add the Describe() method for the following objects?

CollaborationGroupRecord, ContentDocumentLink, ContentFolderItem, ContentFolderMember, ContentHubItem, Datacloud*, DataStatistics, DataType, DcSocialProfile*, EntityDefinition, EntityParticle, FieldDefinition, FlexQueueItem, IdeaComment, KnowledgeArticleVersion, ListViewChartInstance, LoginEvent, OauthToken, PicklistValueInfo, PlatformAction, RelationshipDomain, RelationshipInfo, SearchLayout, TenantUsageEntitlement, UserEntityAccess, UserAppMenuItem, UserFieldAccess, UserProfileFeed, UserRecordAccess, Vote

Hi Thomas , 

Try something as shown below.
  
// sObject types to describe
String[] types = new String[]{'Account','CollaborationGroupRecord','ContentDocumentLink','ContentFolderItem' };

// Make the describe call
Schema.DescribeSobjectResult[] results = Schema.describeSObjects(types);

System.debug('Got describe information for ' + results.size() + ' sObjects.');

// For each returned result, get some info
for(Schema.DescribeSobjectResult res : results) {
    System.debug('sObject Label: ' + res.getLabel());
    System.debug('Number of fields: ' + res.fields.getMap().size());
    System.debug(res.isCustom() ? 'This is a custom object.' : 'This is a standard object.');
    // Get child relationships
    Schema.ChildRelationship[] rels = res.getChildRelationships();
    if (rels.size() > 0) {
        System.debug(res.getName() + ' has ' + rels.size() + ' child relationships.');
    }
}
