[yocto] does a meta-intel (sub)layer require adding the meta-intel layer to bblayers.conf?

hang on ... i can see that meta-intel is a valid layer, under which
you can find conf/machine/include/ia32-base.inc. and in all of the
*specific* intel-related BSPs, well:
$ grep -r ia32-base.inc *
meta-cedartrail/conf/machine/cedartrail.conf:require conf/machine/include/ia32-base.inc
meta-crownbay/conf/machine/crownbay.conf:require conf/machine/include/ia32-base.inc
meta-crownbay/conf/machine/crownbay-noemgd.conf:require conf/machine/include/ia32-base.inc
meta-emenlow/conf/machine/emenlow.conf:require conf/machine/include/ia32-base.inc
meta-fishriver/conf/machine/fishriver.conf:require conf/machine/include/ia32-base.inc
meta-fri2/conf/machine/fri2-noemgd.conf:require conf/machine/include/ia32-base.inc
meta-fri2/conf/machine/fri2.conf:require conf/machine/include/ia32-base.inc
meta-jasperforest/conf/machine/jasperforest.conf:require conf/machine/include/ia32-base.inc
meta-n450/conf/machine/n450.conf:require conf/machine/include/ia32-base.inc
meta-romley/conf/machine/romley.conf:require conf/machine/include/ia32-base.inc
meta-sugarbay/conf/machine/sugarbay.conf:require conf/machine/include/ia32-base.inc
meta-sys940x/conf/machine/sys940x-noemgd.conf:require conf/machine/include/ia32-base.inc
meta-sys940x/conf/machine/sys940x.conf:require conf/machine/include/ia32-base.inc
$
that *would* seem to require adding meta-intel to your layers file,
no? or am i misunderstanding something?
