well, RTOS is mostly required for running other tasks aside from L1 such
as L2, L3, MMI (UI), etc.

Of course you can do that.  But I think after the RTOS port of OsmocomBB
is completed, not many people will still try to maintain the old
pre-RTOS code.

But at least in one version of the new proposed RTOS based firmware, we
would expose the same L1CTL interface via SERCOMM on the UART, so you
could still run the same layer23/mobile stuff on the host PC (or
Openmoko Application Processor).
