Life is a trade-off: someone want a very hard real-time system without
adopt other hardware architectures than pc (MCU, FPGA/ASIC, and so
on), others want use normal and cheap pc, others want use also
accelerated drivers also, others want a real-system which take care of
they laptop's batteries too. And at the end we have limited
resources(*) for give an answer on these needs (we are all

Obviously We can't do all these things so we have to choose: It is sad
but it is the life.

It is on leader, developers team and comunity choose that trade-off.
