What you mean like when AIrbus launched the A3456, then the clean sheet A380 while Boeing launched the 747-8, all with four engines? All after the ETOPs regulations? At the time many considered the first accident would be the end of it. Of course history didn’t have that event so the four engined aircraft died...... it still took 25 years.
