Do they not do passport stamps anymore?

So I recently flew from JFK to Zagreb via Warsaw. My passport never got stamped coming or going in Poland, nor when I landed back in the US.

I haven't been to Europe since 2019, but I traveled there often in the 2010s (7-8 times) and always got my passport stamped both in every European country and when coming back to the US. Has passport stamps been done away with?

It's sad I had a brand new passport I was hoping to get the maiden stamp on. I love looking at my old passports and all the stamps. I'd be sad if this classic travel souvenir has been done away with
