I've never had a bicycle that had a press-fit bottom bracket, they've all been square-taper designs. They range from a 1977 steel Schwinn LeTour Lux to a modern-day 'non-name' cyclocross frame I purchased about 4 years ago and built up myself. The mechanism is in a sealed cartridge, easy to replace with standard tools, and inexpensive, too!.
FWIW: All the bikes I have are equipped with press-fit headsets - will those be going away too, replaced by 'integrated' headsets? I've never ridden a bicycle with an integrated version, but it looks somewhat similar to a press-fit BB arrangement.
