Thank you to everyone who received my suggestions warmly.
Please feel free to send them off to Apple if you wish. I'm planning on sending a lot of feedback to Apple myself, once I get the chance to write it all up.
As far as Darwin and potential incompatibilities from broken hard links go, I don't really think this would be a major concern. Sure, Apple may need to recode some hard links to the System library, but as Starfleet stated, what we see in that folder is pretty high level. Darwin has its own UNIX directory structure that it's much more directly connected to. The changes we've suggested wouldn't be altering that UNIX layer in any significant way.
