  The SUSY flavor, CP, gravitino and proton-decay problems are all solved to
varying degrees by a decoupling solution wherein first/second generation matter
scalars would exist in the multi-TeV regime. Recent models of natural SUSY
presumably allow for a co-existence of naturalness with the decoupling
solution. We show that: if sfermions are heavier than $\sim 10$ TeV, then a
small first/second generation contribution to electroweak fine-tuning (EWFT)
requires a rather high degree of intra-generational degeneracy of either 1.
(separately) squarks and sleptons, 2. (separately) left- and right-type
sfermions, 3. members of SU(5) multiplets, or 4. all members of a single
generation as in SO(10). These (partial) degeneracy patterns required by
naturalness hint at the necessity of an organizing principle, and highlight the
limitations of models such as the pMSSM in the case of decoupled first/second
generation scalars.
