Playfair does have a future if used well, because the Playfair cracker at quinapalus relies on words or phrases appearing in a dictionary. A while ago there was an EV puzzle by Nod, "Snapshot", where the Playfair codeword was "Flash picture by nod" which the cipher can't crack, so that some hand work or some inspiration was needed. Also if it helps to disguise the theme for just a little bit longer, as here, then it's rather like misprints that online crackers can also provide suggestions for.
If it's just "four theme words are encoded by a playfair square to be deduced" where the theme words are duck, spin, bowler and wicket with a codeword of umpire then yes it's nothing to write home about, but here or in the recent Magpie with a Playfair cipher going on (Enimga Variations by Ferret), it's a little bit more than that and adds a nice touch to the puzzle.
