Odd behavior with SOFTDEVICE_HANDLER_INIT w/o Scheduler

[Locky]

When I initialize the SoftDevice with SOFTDEVICE_HANDLER_INIT(NRF_CLOCK_LFCLKSRC_XTAL_20_PPM, false); // Sets up Crystal Source to 20ppm 32.7628kHz

The project I based my code on had the scheduler parameter USE_SCHEDULER = false

However my application is using the Scheduler for Application level event handling. What are the implications (negative) of using the Scheduler for only Application level events, while disabling the SoftDevice from using the Scheduler?
