Bad.  Very bad.

So, when I use PIO IDE on embedded platforms, I have to have all other
interrupts locked out for things like serial ports, network interfaces
with small packet buffers, etc and I can't specify IRQF_DISABLE on
such network interfaces anymore?

No, this is a step backwards.  Please don't go there.
