I find the paragraph above to be identical in result to my straw
man #2 proposal.  I would not object to using this language;
particularly if it results in more consensus.

I believe regardless of the size of allocation from LIR -> End Site
the HD Ratio allows the LIR to hold some /48's in reserve.  I
personally belive the two issues are completely unrelated.
