Haven't read Swensen's book, but this seems to go against the whole idea of diversification.
Sometimes treasuries outperform spread products, but lots of times they don't. Wouldn't you want exposure to all of them?
It's true one would give up some diversification by avoiding non treasury FI.
But IMO one doesn't need to buy every asset class to be well diversified. I like the idea of being well diversified in the high return, high risk asset classes, and for low risk, low return classes, just going for safety. (of course, there's still interest rate risk and reinvestment-interest-rate risks, but at least one avoids credit risks with treasuries.)
Swensen makes the points MasterBlaster states, and others, including alignment of interests between small investor and whoever's offering the investment.
Not all gurus agree on this, by any means.
IMO probably any asset class could be appropriate, at the right price. I'm no expert, but at today's prices, corporate bond funds (including high-yield, and total bond index which includes corp and asset backed) don't make any sense to me.
If one were to choose a static Strategic Asset Allocation, I think it could make sense to avoid asset classes which are seldom priced to be sensible investments for the individual investor. Swensen includes corp FI in things to leave out. (And W.Bernstein, long term bonds, I believe.)
