Athematic PIE 2sg imperative

AfaIk the consensus is that the PIE 2sg imperative suffix was *-dhi.
But Jasanoff discusses some in *-si (eg Hittite pahsi "protect!").
I was wondering if the PIE suffix wasn't *-i, or rather an ablauting
*-ei/*-i (cf Russian derz^í, búd´), and that *-dhi was instead the
imperative of *dheh1- "put" (which I suspect is also behind various
past suffixes in the style of *-ta)?
