An if node at the bottom of the stream is actually A GREAT solution, and we have many standard graphs built procedurally that always feature one in a name coded compound. Not only it allows you to force a bottom-most pull reliably at your convenience, it also makes sure you can always reliably disable/enable graphs procedurally at a whim without having to deal with the often finnicky operator stack.
A compound with two ports, an if evaluated one and a pass through, costs nothing in performance and is a great way of comforming graphs and gaining control over their eval without going insane trying to script within the domain of an ICE tree (which is by its nature tricky at the best of times).
