Marcus, i think that full or 'dev' images just need to have a
configurations which people could load on top of core image.
The responsibility of core team is to define what is included in those
configurations on next release and
making sure that they can be loaded in latest core images.

But don't mix 'can be loaded' with 'works without bugs' :) This is
another story. This is where community has to be involved and people
who interested in
using full image(s) need to help with it.
Otherwise, if nobody using it, then why wasting an effort with
maintaining and fixing such a large codebase?

I know it by myself, that bugs are discovered and fixed only when you
using some tool(s). But if something lies there unattended, then it
will definitely
break at some point, and it is not really matters how hard you try to
keep backwards compatibility or making sure all tests are green.
