While I understand and agree with most of your points… The title chosen by the OP implies that the “Extras” have no value but only cause frustration.
Which makes no sense: If they have no value, there’s no reason to complain, one can simply ignore them. If they do have value, then they can’t be a constant (!) source of frustration.
The extras are something that is offered, not an obligation. So, recognizing the effort might be a nicer attitude than complaining about perceived shortcomings. Telling someone that their work causes only frustration and irritation is not motivating.
