Meta-oe has far to many recipes for some people to want
to include the entire layer:
    meta-oe.git $ find meta-oe/ -name "*bb" | wc -l
    618
We can certainly use the new whitelist layer filtering to
get to a smaller collection of recipes but I'd like to suggest we
need to document and maybe design the layer structure
a bit more. There are lots of different opinions about
how to split collections of packages in to different layers so
unless someone has a dependency-based analysis of all
pacakges in all layers, I don't see much point in a long
discussion on this topic.

Has the idea of creating a new meta-openembedded layer
for widely-used, OS interface libraries been proposed?
These 80 recipes could be considered for inclusion:
    $ find  meta-oe -name "lib*bb" | wc -l
    80
but more consideration is probably needed.

In the short term (oe-core-1.9 (now 2.0), I guess we leave
things as they are. Sigh...

While I'm at it, for reference of layer size:

$ for i in `ls -d meta-*`; do echo -n $i": "; find $i -name "*bb" | wc 
-l; done

meta-filesystems: 16
