-------------------------------------------------------------------

Here is fewer-impact approach induced by chat with [~osavrasov]. The proposal is to introduce
{{json.queries}}, it's like arbitrary {{json.param}} but it's translated with query DSL 

{code}
{
    "query" : {
      "#top":{
          "parent": {
              "query": "sku-title:foo",
              "filters" : "$childFq", // non-json old style param reference 
              "which": "scope:product"
           }
        }
    }, // like .param but parsed with query dsl syntax 
    "queries":{
         "childFq":[{ "#color" :"color:black" },
                    { "#size" : "size:L" }]
    },
    "facet":{
       "sku_colors_in_prods":{
          "type" : "terms",
          "field" : "color",
          "domain" : {
               "excludeTags":["top",       // we need to drop top-level parent query
                              "color"],    // excluding one child filter clause
               "filter":[ 
                      {"param":"childFq"}  // referring to .queries.childFq
               ]
           },
        "facet": {                         // counting products
              "prod_count":"uniqueBlock(_root_)"
           }
   }
}
}
{code}

> h2. Problem
> # after SOLR-9685 we can tag separate clauses in hairish queries like {{parent}}, {{bool}}
> # we can {{domain.excludeTags}}
> # we are looking for child faceting with exclusions, see SOLR-9510, SOLR-8998    
> # but we can refer only separate params in {{domain.filter}}, it's not possible to refer
separate clauses
> h2. Proposal
