Yes, this is another valid point. We have already identified that many things in OE are a bit
tailored to u-boot. Having another option (as one has for x86 with grub anyway) could, especially on
ARM platforms, inspire to make things more generic and probably also create community synergy
effects.

What clearly would not be the intention is to tailor things in oe-core for barebox only.

Yes, I stated that this is clearly our intention.
So support isn't only a one-man show at all ;)


Thanks and best regards, Enrico
