> It would sure be possible to always re-initialize the PLL when when a interrupt has triggered a wake-from sleep, we are still in control of the IRQ handler (which would of course delay that interrupt - depends on the application if that is acceptable).

Note that RIOT is intended to be used as general purpose OS. Doing so would conflict with this.

Btw: What are the use cases for STDIO access during ISR except for debugging? IMO, we should just add the warning and spend our time on more pressing stuff.
