Long ago I made a 6" f/8, 8" f/7, 4" f/2.8, 6" f/5 and then converted the 6" f/5 to f/19.
I HATE diffraction spikes and to me they are the sign of a very lazy telescope maker who doesn't know any better.
if you like them... well... thats up to you. If you want really huge SPIKES put a square or hexagonal mask in front of your scope.
FWIW I know someone who used to put a hexagonal mask on a Celestron deliberately to ADD diffraction spikes - don't ask me why as I have no idea after 30 years.
