The odds of having a problem are low, but of course not zero. When they inspected it, Velosmith thought the Ultegra crank on my bicycle - purchased in 2018 - might be a candidate for replacement. They sent it to Shimano for further evaluation earlier this month, and indeed it was. I’ve gotten the bicycle back now with new cranks and chainrings. 

I hadn't given this recall notice much thought since my Shimano Ultegra crankset first passed inspection shortly after the notice was issued in Fall 2023. But when I took my bike to the shop last week, the mechanic re-inspected the crank as part of the shop's routine service and determined that it now definitely needs to be replaced. The old crank is on its way to Shimano; the new one should arrive next week; and the replacement part and installation cost will be free of charge. If your bike has one of the listed pre-2019 Ultegra or Dura-Ace cranks, you should continue to have it inspected periodically.
