can you elaborate on your reasoning that FK constraints should be used less
overall?  or do you just mean that the client side should be mirroring the same

I don't think he means that we will use them less.  Our SQL backends are full of them.  What Keystone can't do is rely on them because not all implementations of our backends support FKs.
100% spot on David. We support implementations that have no real concept of FK and we cannot assume that a cascade (or restrict) will occur on these implementations.
