Many of my era thought that the proliferation of badges was undesirable. Like medals for crossing the Atlantic and rifle shooting - yet another American influence on the good old RAF tradition of minimum bull****.
One particular abhorrence was the “hours flown on type badge”, showing off that the aircrew in question had so many thousand hrs on a particular type.
My suggestion at the time - sadly not followed up - was that each aircrew member would wear a smart badge in which the number of hours shown could be increased after each flight. Hence, for example, Fg Off Farnes-Barnes (469 hrs on type) could lord it over Plt Off Prune with only 397 hrs.
I still think it’s a good idea.
