I hope the latter, but this is not fully ironed out.

You're welcome! Glad you like it (that reminds me that I still have to
add last weeks result to the table)

My impression would be that the slugos layer would only contain the
slugos distro specific stuff.
E.g. things like conf/distro/slugos.conf and what is included by it,
and slugos specific recipes (probably things like upslug2, although
technically they are nslu2 specific not slugos specific, so they could
also go into an nslu2 machine layer).
But this has not really been discussed as far as i recall.

I hope not. Actually as OE-core has also the yocto momentum behind it
I guess that forks will probably die because the additional effort is
not available or does not pay off well.
Preferably we should keep it one repo.
Having a good maintainer/integrator also helps (with authority and
good judgement).
The process for OE-core would probably be similar to what u-boot and
the kernel do.

This is definitely  an issue we need to address.

I'd hope there is lots of sharing and little effort needed to create a
new layer.

Enjoy, Frans.
