> In Solr 7 we can't index boost as it's gone from Lucene. The JSON support for this syntax
is still allowed but logs a warning and doesn't apply the boost (as it's not supported). I'm
proposing we remove support for this altogether. This also means removing an little-known
way to specify an "extended field value" that doesn't necessarily have a boost.
>  With boost: Today logs a warning. *Don't want this to work at all.*
> {code:java}
> [{'id':'1', 'val_s':{'value':'foo', 'boost':2.0}}]
> {code}
> Without boost: Today works. *Don't want this to work at all,* as it complicates support
for labelled child documents – SOLR-12362.
> {code:java}
> [{'id':'1', 'val_s':{'value':'foo'}}]
> {code}
> Internally this is parsed by
>  org.apache.solr.handler.loader.JsonLoader.SingleThreadedJsonLoader#parseExtendedFieldValue
>  I think we need make no reference to the notion of an "extended field value". Either
we have a "partial update", or we have a "child document"; nothing else.
> [https://lucene.apache.org/solr/guide/7_3/updating-parts-of-documents.html]
> Note: partial updates look similar and have exactly one field-value using a limited set
of verbs like "set":
> {code:java}
> [{'id':'1', 'val_s':{'set':'foo'}}]
> {code}
