So now I am using this set of nodes - here are my thoughts. (Spoiler - I'm liking it)
-
It should really be called
node-red-contrib-subroutine(IMO) as that is pretty much what it does... -
unlike a subflow where you cant choose
msgorflowas an input, you can with this node - very nice touch...Setup (comp start node)...
Using it (use comp node)...
Apart from the odd naming of nodes...
... this is a pretty good set of nodes.
Me likey - a lot 
PS, if i were pushed for alternative naming, it'd be...
node-red-contrib-components --> node-red-contrib-subroutine
comp start --> Subroutine Define
comp return --> Subroutine Return
use comp --> Subroutine Call
