I think that Siliconix didn't think it was important enough to
mension or perhaps they measured the recovery and decided just
not to bring the subject up.

I got bitten by Siliconix when trying to use the
VN10KM as a direct replacement for a JFET bipolar
analogue switch. The presence of a shunt body diode
is not acknowleged on any Siliconix VMOS data sheet,
but there is a mention in one of their app notes.

A similar situation exists with Zetex DMOS Fets.
There is no explicit mention of a body diode in the
process.... you have to notice that some data sheets
carry an added a Source-Drain Diode spec.
