[reactive] Is Arrow based FRP a subset of Classic FRP, at least conceptually/semantically?

Classic FRP ("CFRP", like Fran, FAL, Reactive, Grapefruit?...) exposes signals as first class values. Arrow based FRP ("AFRP", like Fruit, Yampa...) hides signals as first class values; instead the signal transformers are the first class values. Can I conclude that it would theoretically be possible to translate an AFRP function into a CFRP function? I.e. is AFRP a subset of CFRP? Thanks, Peter
