Given the timeframe it would be odd if they didn't.I really hope we are actually getting a pre-Disco looking Klingon on the series.
I get why people would feel that the Klingons are overused, counting Worf and B'Elanna they're in something like 60% of all Star Trek stories, but they're one of the major neighbouring empires so it'd be a bit weird if they didn't keep showing up from time to time.
