Do disconnected nodes get compiled or built?

What I want to know is does it take extra time during compiling or building a project to have disconnected blueprint nodes hanging about from previous code that is not currently in use. A firmer example would be a print string that has a string connected to it but no exec

If disconnected nodes aren’t setup properly then they will generate compiler errors. To me, this demonstrates the fact that they aren’t being ignored when the game is compiled.
