Not an actual bug in optiboot, and no code changes to the repository are 
anticipated.  However, you should be able to do this by changing the code at 
the start of main() from:
  // Adaboot no-wait mod
  ch = MCUSR;
  MCUSR = 0;
  if (!(ch & _BV(EXTRF))) appStart();
To something like (untested!):
  // Enter bootloader expect on WDT timeout
  ch = MCUSR;
  MCUSR = 0;
  if ((ch & _BV(WDRF))) appStart();

(this is supposed to say: start the app only if the reset reason was a watchdog 
timeout.)
