A fine criteria except for the fact that the rpis have some special problems - the combination of low(ish) ram and unreliable storage? So you can't (shouldn't) expand ram via disk (eats the SD card) - and need to fit everything in ram. This is different from a typical low end netbook/laptop - which might have more ram, and reliable, fast (compared to mechanical hdds) reliable storage (cheap ssd).
In principle I agree - rpis are small/lightweight - but I'm afraid distros would do better targeting rpi or typical "small pc".
Ed: that said, this is (like puppy) designed to run from USB stick, in ram, with a section for user data:
> The default mode is to have a "save" icon on the desktop, to flush RAM to drive whenever you want, or not at all, or at shutdown. Thus, writes to the drive are severely constrained.

I'm not sure if it has the option to limit writes, like puppy?:
