Description
UpdateRequestProcessors completely ignore child documents. The only exception is AddSchemaFieldsUpdateProcessorFactory. The rest seem to be completely unaware that SolrInputDocument has getChildDocuments() or related methods.
Easy test (on Solr 6.2):
This works (with IDs auto-assigned and field names generated):
bin/solr create -c childtest
bin/post -c childtest -type application/json -format solr -d '[{"a":1,"b":2}]'
This fails as the second/third command, with "missing ID field":
bin/post -c childtest -type application/json -format solr -d '[{"a":1,"b":2,"_childDocuments_":[{"c":3,"d":4}]}]'
The message:
SimplePostTool version 5.0.0

I also verified it with BlankRemoving URP. I think this is a global problem.
