In that case, there is a dedicted, records-specific API to retrieve the name of “record components”, which happen to also be the name of parameters to the canonical constructors. We could leverage that as a source of information for the name of constructor parameters, thereby making projection constructors work (at least in this specific case) even when -parameters was not used during compilation.
