It's not surprising because there's no demand for it. A number of commercial
(crypto hardware) products do it, but only as a backup mechanism / to allow
key migration into new hardware units. Every vendor has their own techniques
for this, which fit their existing key management mechanisms. I talked to
some people about doing a standard for this a while back, but given the vast
number of implementation details you'd have to accomodate and the absence of
demand for it, it never went any further than that.
