You can do a fairly good emulation of a closed transfer by ensuring you purge your cornie with CO2 a few times. Then you are transferring into a cornie full of CO2 so little oxygen can get to it.
The instructions won't mention a D-rest to keep the instructions simple and cater for people (probably the majority) who don't have temperature control. Raising the temperature towards the end of fermentation accelerates the process of the yeast 'tidying up'. It still happens at the fermentation temperature but more slowly.
