> Portability allows the whole FOSS ecosystem to evolve and adapt.
Amen. Without portability we wouldn't where we are now. More importantly, we will eventually be boned without it. Sooner or later Linux comes to the end of the road. The landscape will eventually change such that someone will realize it is time for a total redesign of what an OS is and if nothing is portable that new effort will fail, leaving us in a dead end to wither away.
