Ya, come to think of it, something like (where "foo" is in OVERRIDES):

 BBAPPENDPATHS_foo += "${LAYERDIR}/foo/recipes-*/*/*.bbappend"

might be better for that reason. It would move the exponential search
into bitbakes variable cache in memory instead of having to search the
disk

I'm not too familiar with mutliconfig, but that does seems like it
would need to be solved... does this stem from all of them sharing a
bblayer.conf, and hence everyone currently gets the same BBPATH?. It
seems like allowing config specific BBPATHS (or BBAPPENDPATHS) might
be able solve that problem? That might even be a more targeted
solution to the problem that trying to solve it for conditional
includes.
