I think implementing a workaround like that would just confuse the 
situation even more. I can easily imagine hours wasted digging around in 
/etc trying to figure out why some programs work properly and others don't.

That's an even worse idea, because then we're making programs work 
around systemd's decisions. Interoperability and maintenance nightmare, 
not to mention the numerous philosophical objections I could think of.

If this were a badly needed architectural change, it might be worth 
considering these ideas. But there's so little benefit to this behaviour 
that it's simply not worth making the effort to adapt to.
