Sure. The caller doesn't much care whether the callee is a builtin,
function, an alias, a script, a compiled binary, or whatever; execution
resumes after it exits. You can make it exit immediately by calling it as
"whatever &" instead of "whatever".

You don't have to comment out anything except the actual execution, no,
but to prevent confusion in the future about "I wonder why that is
commented out; none of the other stuff relating to it is", I would.

Probably. Hard to say without seeing it.
