Has this changed with jet engines ? I would have though that it would
still have been during takeoff that jet engines failed. (Although one
could contend that during landing, when thrust reversers are deployed,
there would be stress too).

Since the purpose of ETOPS is to allow planes to go far, we're talking
about low number of cycles and high number of hours. Perhaps statistics
look less scary when you're talking number of hours as opposed to number
of flights.
