Thanks David, I have updated the wiki documentation http://wiki.apache.org/solr/DataImportHandler#transformer
The default transformers do not have any special privilege it is like any normal user provided transformer.We just identified some commonly found usecases and added transformers for that. Applying a transformer is not very 'cheap' it has to do extra checks to know whether to apply or not.
