Well the issue to update rpi to stretch in gh is open for 1.5 years.

No. IMO you should use an old version of isar for old stuff. Trying to 
be backwards compatible as long as possible it not something isar<1.0 
should try to do anyway, but I would argue that isar>1.0 should also 
restrict.

Isar breaks the layer interface currently to often that it does not make 
any sense to be coy about breaking board support if necessary.

Great if updating rpi to stretch is not a problem, then this patch is 
not needed!

Well my intention for the removal patch was, that it will take about a 
week before it is merged and if raspberry pi is updated to stretch 
before that, then this patch is no longer needed.

I submitted this revision of the patch after I saw that the issue to 
upgrade rpi to stretch is now 1.5 years old. And I really don't want to 
wait such periods until we can drop jessie support. I hope you understand.

regards,
Claudius
