That would be great!

I am not against adding fields to query_params. However, we have a standard way to specify the RID components like LID which should be followed.

If you need new components to be specified for new attributes it is fine to add them to query_params. That said, any components which already have options should be overloaded; for example MultiPathRecord.SL should use the --sl option.

Does this make sense?
