Should we set the listen handler to zero after removing it?

I've come across some scripts where the author explicitly sets the handler to zero after releasing it, e.g.:

// [...]
gChannel = -123456789;
gDialogListener = llListen(gChannel, "", NULL_KEY, "");
// [...]
listen(integer channel, string name, key id, string message)
    gDialogListener = 0;
    // [...]

In my view, whatever the channel was before removing it, it is gone forever afterwards, i.e. there is no need to 'reset' it (also, why reset it to zero? Zero might be a valid handler ID... or isn't it?).

Am I right, or have LSL programming practices changed since I last looked this up? 🤓
