I never argued that it was. Though, "embedded" covers a wide spectrum of systems. For microcontroller-based projects, then no. For bigger SoCs paired with hundreds of MBs of FLASH/RAM it can be very useful.

My original point was that claiming that Linux is partially modular while RIOT is fully modular feels like a stretch to show N lines of red crosses and orange circles, followed by one line of only green check marks.

Linux's FLASH/RAM requirements are enough to disqualify it from projects targeted by RIOT, IMHO. No need to make dubious claims of limited modularity.
