I think that inconsistency is untenable. If nothing else, it means your 
changes will get broken by other people who also apply constraints 
inconsistently.

I think you need to consider what happens when you apply this regime 
tree-wide. Either that or explain why it would make sense to build e.g. 
drivers/s390 but not drivers/s390/net.
