Parsing time and probably memory used scale ~ linearly with the number
of recipes, so that's a *bit* of a concern especially since it's

As Mark said, it's a business decision.
There are (probably more than linear) engineering costs to
adding a recipe to a distribution. That's why we were using
the meta-FOO-subset approach.
Of course, personally I'd like to provide the full set of
meta-openembedded layers and more! We might be able to support
all of meta-openembedded at some point but I don't think it's
the right decision now.
