No, there are no plans to cascade GetFeatureInfo requests. The reason is 
that the specification doesn not define the format for the 
GetFeatureInfo response, so there is no way that MapServer can 
predictably ingest the response and cascade or do something with it.

Instead, MapScript provides a $layer->getWMSFeatureInfoUrl() method that 
will build the GetFeatureInfo request URL for you. You can then call 
that URL from your script and try to do something with the response.
