I suggest 45cm chain stays were the longest ones commercially used since the 1970's since normal front ring was 52t, largest cog 34T (for touring & hills) and standard chain lengths were packaged at 116L, the value using the standard formula 2*Lstay +(Fl +Rl)/4 +1, for a 45cm stay.
Longer stays would require longer chains, so perhaps the manufacturers thought 45cm was long enough. Most JoeyA riders have commented on the need for chains > 116L. If specing a bike now with a 42T front (100gi, 11T small rear) and 34T large rear, 116L chain requires a Stay length of <= 48.3cm using the chain length formula.
