it would be interesting however I think this should be a default
optout feature with possibility to optin
so probably what you have is an ok approach. Somehow we should have a
global knob controlled
by distros to specify what language environments to enable

yeah those are complications either you can demand those from build distro
by adding them to required_software in sanity class or you can provide a -native
recipe and then DEPEND on that one first one would be easier

they would be in bitbake.conf or base class.
