nRF52 LF crystal oscillator

What are the consequences of not using the optional 32KHz crystal oscillator in the nrf52 reference design.

Do you plan to use internal RC oscillator instead ? These typically have to be calibrated at 4s interval and that leads to increase in current consumption.

Personally I've not noticed the impact of this on battery life (I'm using nrf51 still) but it should show up
