ISET behavior related to PGFB level

Almost all LT30xx series low noise LDO regulator datasheets on the fast startup section says:

The 2 mA current source remains engaged while PGFB is less than 300 mV, unless the regulator is in current limit, dropout, thermal shutdown, or the input voltage is less than the minimum V_IN.

Therefore it may cause two possible situation in application circuit:

1. PGFB setpoint lower than R_SET×100μA

   This should give no problem. PG will assert slightly earlier. Fast startup will terminate earlier, but VOUT should still ramp up with the slower 100μA slope

2. PGFB setpoint higher than R_SET×100μA

   This is the one I'm not sure about. In this case PG should never get asserted. The datasheet wording and a look at functional block diagram may give the impression that VOUT may overshoot the R_SET×100μA setpoint since the 2mA fast startup current may still active.
   However that's NOT how it behave in LTSpice. V_OUT still accurately follow R_SET×100μA setpoint. So, Can something else other than PGFB threshold disable fast startup current source?

For obvious reason it's clear that best practice is to set PGFB threshold slightly lower than V_OUT setpoint, but I want to know how exactly the device is behaving in the second case. Is the LTSpice model behavior guaranteed?

On another note, any particular reason why LT3097 got removed from LTSpice default library?
